Methods

AbortMultipartUploadAsync(AbortMultipartUploadRequest, CancellationToken)

This action aborts a multipart upload. After a multipart upload is aborted, no additional parts can be uploaded using that upload ID. The storage consumed by any previously uploaded parts will be freed. However, if any part uploads are currently in progress, those part uploads might or might not succeed. As a result, it might be necessary to abort a given multipart upload multiple times in order to completely free all storage consumed by all parts.

To verify that all parts have been removed, so you don't get charged for the part storage, you should call the ListParts action and ensure that the parts list is empty.

For information about permissions required to use the multipart upload, see Multipart Upload and Permissions.

The following operations are related to

AbortMultipartUpload

:

• CreateMultipartUpload

• UploadPart

• CompleteMultipartUpload

• ListParts

• ListMultipartUploads

public virtual Task<AbortMultipartUploadResponse> AbortMultipartUploadAsync(AbortMultipartUploadRequest request, CancellationToken cancellationToken = default)

Parameters

request AbortMultipartUploadRequest

Container for the necessary parameters to execute the AbortMultipartUpload service method.

cancellationToken CancellationToken

A cancellation token that can be used by other objects or threads to receive notice of cancellation.

Returns

Task<AbortMultipartUploadResponse>

The response from the AbortMultipartUpload service method, as returned by S3.

public virtual Task<AbortMultipartUploadResponse> AbortMultipartUploadAsync(string bucketName, string key, string uploadId, CancellationToken cancellationToken = default)

Parameters

bucketName string

The bucket name to which the upload was taking place. When using this action with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.Region.amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide. When you use this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form

AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com

. When you use this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts in the Amazon S3 User Guide.

key string

Key of the object for which the multipart upload was initiated.

uploadId string

Upload ID that identifies the multipart upload.

cancellationToken CancellationToken

A cancellation token that can be used by other objects or threads to receive notice of cancellation.

Returns

Task<AbortMultipartUploadResponse>

The response from the AbortMultipartUpload service method, as returned by S3.

REST API Reference for AbortMultipartUpload Operation

CompleteMultipartUploadAsync(CompleteMultipartUploadRequest, CancellationToken)

Completes a multipart upload by assembling previously uploaded parts.

You first initiate the multipart upload and then upload all parts using the UploadPart operation. After successfully uploading all relevant parts of an upload, you call this action to complete the upload. Upon receiving this request, Amazon S3 concatenates all the parts in ascending order by part number to create a new object. In the Complete Multipart Upload request, you must provide the parts list. You must ensure that the parts list is complete. This action concatenates the parts that you provide in the list. For each part in the list, you must provide the part number and the

ETag

value, returned after that part was uploaded.

Processing of a Complete Multipart Upload request could take several minutes to complete. After Amazon S3 begins processing the request, it sends an HTTP response header that specifies a 200 OK response. While processing is in progress, Amazon S3 periodically sends white space characters to keep the connection from timing out. A request could fail after the initial 200 OK response has been sent. This means that a

200
                                                                                    OK

response can contain either a success or an error. If you call the S3 API directly, make sure to design your application to parse the contents of the response and handle it appropriately. If you use Amazon Web Services SDKs, SDKs handle this condition. The SDKs detect the embedded error and apply error handling per your configuration settings (including automatically retrying the request as appropriate). If the condition persists, the SDKs throws an exception (or, for the SDKs that don't use exceptions, they return the error).

Note that if

CompleteMultipartUpload

fails, applications should be prepared to retry the failed requests. For more information, see Amazon S3 Error Best Practices.

You cannot use

Content-Type: application/x-www-form-urlencoded

with Complete Multipart Upload requests. Also, if you do not provide a

Content-Type

header,

CompleteMultipartUpload

returns a 200 OK response.

For more information about multipart uploads, see Uploading Objects Using Multipart Upload.

For information about permissions required to use the multipart upload API, see Multipart Upload and Permissions.

CompleteMultipartUpload

has the following special errors:

• Error code:

  EntityTooSmall

  • Description: Your proposed upload is smaller than the minimum allowed object size. Each part must be at least 5 MB in size, except the last part.

  • 400 Bad Request

• Error code:

  InvalidPart

  • Description: One or more of the specified parts could not be found. The part might not have been uploaded, or the specified entity tag might not have matched the part's entity tag.

  • 400 Bad Request

• Error code:

  InvalidPartOrder

  • Description: The list of parts was not in ascending order. The parts list must be specified in order by part number.

  • 400 Bad Request

• Error code:

  NoSuchUpload

  • Description: The specified multipart upload does not exist. The upload ID might be invalid, or the multipart upload might have been aborted or completed.

  • 404 Not Found

REST API Reference for CompleteMultipartUpload Operation

CopyObjectAsync(CopyObjectRequest, CancellationToken)

Creates a copy of an object that is already stored in Amazon S3.

note

You can store individual objects of up to 5 TB in Amazon S3. You create a copy of your object up to 5 GB in size in a single atomic action using this API. However, to copy an object greater than 5 GB, you must use the multipart upload Upload Part - Copy (UploadPartCopy) API. For more information, see Copy Object Using the REST Multipart Upload API.

All copy requests must be authenticated. Additionally, you must have read access to the source object and write access to the destination bucket. For more information, see REST Authentication. Both the Region that you want to copy the object from and the Region that you want to copy the object to must be enabled for your account.

A copy request might return an error when Amazon S3 receives the copy request or while Amazon S3 is copying the files. If the error occurs before the copy action starts, you receive a standard Amazon S3 error. If the error occurs during the copy operation, the error response is embedded in the

200 OK

response. This means that a

200 OK

response can contain either a success or an error. If you call the S3 API directly, make sure to design your application to parse the contents of the response and handle it appropriately. If you use Amazon Web Services SDKs, SDKs handle this condition. The SDKs detect the embedded error and apply error handling per your configuration settings (including automatically retrying the request as appropriate). If the condition persists, the SDKs throws an exception (or, for the SDKs that don't use exceptions, they return the error).

If the copy is successful, you receive a response with information about the copied object.

note

If the request is an HTTP 1.1 request, the response is chunk encoded. If it were not, it would not contain the content-length, and you would need to read the entire body.

The copy request charge is based on the storage class and Region that you specify for the destination object. For pricing information, see Amazon S3 pricing.

Amazon S3 transfer acceleration does not support cross-Region copies. If you request a cross-Region copy using a transfer acceleration endpoint, you get a 400

Bad
                                                                                      Request

error. For more information, see Transfer Acceleration.

Metadata

When copying an object, you can preserve all metadata (default) or specify new metadata. However, the ACL is not preserved and is set to private for the user making the request. To override the default ACL setting, specify a new ACL when generating a copy request. For more information, see Using ACLs.

To specify whether you want the object metadata copied from the source object or replaced with metadata provided in the request, you can optionally add the

x-amz-metadata-directive

header. When you grant permissions, you can use the

s3:x-amz-metadata-directive

condition key to enforce certain metadata behavior when objects are uploaded. For more information, see Specifying Conditions in a Policy in the Amazon S3 User Guide. For a complete list of Amazon S3-specific condition keys, see Actions, Resources, and Condition Keys for Amazon S3.

note

x-amz-website-redirect-location

is unique to each object and must be specified in the request headers to copy the value.

x-amz-copy-source-if Headers

To only copy an object under certain conditions, such as whether the

Etag

matches or whether the object was modified before or after a specified date, use the following request parameters:

• x-amz-copy-source-if-match

• x-amz-copy-source-if-none-match

• x-amz-copy-source-if-unmodified-since

• x-amz-copy-source-if-modified-since

If both the

x-amz-copy-source-if-match

and

x-amz-copy-source-if-unmodified-since

headers are present in the request and evaluate as follows, Amazon S3 returns

200
                                                                                          OK

and copies the data:

• x-amz-copy-source-if-match

  condition evaluates to true

• x-amz-copy-source-if-unmodified-since

  condition evaluates to false

If both the

x-amz-copy-source-if-none-match

and

x-amz-copy-source-if-modified-since

headers are present in the request and evaluate as follows, Amazon S3 returns the

412 Precondition Failed

response code:

• x-amz-copy-source-if-none-match

  condition evaluates to false

• x-amz-copy-source-if-modified-since

  condition evaluates to true

note

All headers with the

x-amz-

prefix, including

x-amz-copy-source

, must be signed.

Server-side encryption

Amazon S3 automatically encrypts all new objects that are copied to an S3 bucket. When copying an object, if you don't specify encryption information in your copy request, the encryption setting of the target object is set to the default encryption configuration of the destination bucket. By default, all buckets have a base level of encryption configuration that uses server-side encryption with Amazon S3 managed keys (SSE-S3). If the destination bucket has a default encryption configuration that uses server-side encryption with an Key Management Service (KMS) key (SSE-KMS), or a customer-provided encryption key (SSE-C), Amazon S3 uses the corresponding KMS key, or a customer-provided key to encrypt the target object copy. When you perform a CopyObject operation, if you want to use a different type of encryption setting for the target object, you can use other appropriate encryption-related headers to encrypt the target object with a KMS key, an Amazon S3 managed key, or a customer-provided key. With server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts the data when you access it. If the encryption setting in your request is different from the default encryption configuration of the destination bucket, the encryption setting in your request takes precedence. If the source object for the copy is stored in Amazon S3 using SSE-C, you must provide the necessary encryption information in your request so that Amazon S3 can decrypt the object for copying. For more information about server-side encryption, see Using Server-Side Encryption.

If a target object uses SSE-KMS, you can enable an S3 Bucket Key for the object. For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide.

Access Control List (ACL)-Specific Request Headers

When copying an object, you can optionally use headers to grant ACL-based permissions. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API.

If the bucket that you're copying objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don't specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the

bucket-owner-full-control

canned ACL or an equivalent form of this ACL expressed in the XML format.

For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide.

note

If your bucket uses the bucket owner enforced setting for Object Ownership, all objects written to the bucket by any account will be owned by the bucket owner.

Checksums

When copying an object, if it has a checksum, that checksum will be copied to the new object by default. When you copy the object over, you may optionally specify a different checksum algorithm to use with the

x-amz-checksum-algorithm

header.

Storage Class Options

You can use the

CopyObject

action to change the storage class of an object that is already stored in Amazon S3 using the

StorageClass

parameter. For more information, see Storage Classes in the Amazon S3 User Guide.

Versioning

By default,

x-amz-copy-source

identifies the current version of an object to copy. If the current version is a delete marker, Amazon S3 behaves as if the object was deleted. To copy a different version, use the

versionId

subresource.

If you enable versioning on the target bucket, Amazon S3 generates a unique version ID for the object being copied. This version ID is different from the version ID of the source object. Amazon S3 returns the version ID of the copied object in the

x-amz-version-id

response header in the response.

If you do not enable versioning or suspend it on the target bucket, the version ID that Amazon S3 generates is always null.

If the source object's storage class is GLACIER, you must restore a copy of this object before you can use it as a source object for the copy operation. For more information, see RestoreObject.

The following operations are related to

CopyObject

:

• PutObject

• GetObject

For more information, see Copying Objects.

public virtual Task<CopyObjectResponse> CopyObjectAsync(CopyObjectRequest request, CancellationToken cancellationToken = default)

Parameters

request CopyObjectRequest

Container for the necessary parameters to execute the CopyObject service method.

cancellationToken CancellationToken

A cancellation token that can be used by other objects or threads to receive notice of cancellation.

Returns

Task<CopyObjectResponse>

The response from the CopyObject service method, as returned by S3.

A property of CopyObjectRequest used to execute the CopyObject service method.

sourceKey string

A property of CopyObjectRequest used to execute the CopyObject service method.

sourceVersionId string

A property of CopyObjectRequest used to execute the CopyObject service method.

destinationBucket string

The name of the destination bucket. When using this action with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.Region.amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide. When you use this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form

AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com

. When you use this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts in the Amazon S3 User Guide.

REST API Reference for CopyObject Operation

CopyObjectAsync(string, string, string, string, CancellationToken)

Creates a copy of an object that is already stored in Amazon S3.

note

You can store individual objects of up to 5 TB in Amazon S3. You create a copy of your object up to 5 GB in size in a single atomic action using this API. However, to copy an object greater than 5 GB, you must use the multipart upload Upload Part - Copy (UploadPartCopy) API. For more information, see Copy Object Using the REST Multipart Upload API.

All copy requests must be authenticated. Additionally, you must have read access to the source object and write access to the destination bucket. For more information, see REST Authentication. Both the Region that you want to copy the object from and the Region that you want to copy the object to must be enabled for your account.

A copy request might return an error when Amazon S3 receives the copy request or while Amazon S3 is copying the files. If the error occurs before the copy action starts, you receive a standard Amazon S3 error. If the error occurs during the copy operation, the error response is embedded in the

200 OK

response. This means that a

200 OK

response can contain either a success or an error. If you call the S3 API directly, make sure to design your application to parse the contents of the response and handle it appropriately. If you use Amazon Web Services SDKs, SDKs handle this condition. The SDKs detect the embedded error and apply error handling per your configuration settings (including automatically retrying the request as appropriate). If the condition persists, the SDKs throws an exception (or, for the SDKs that don't use exceptions, they return the error).

If the copy is successful, you receive a response with information about the copied object.

note

If the request is an HTTP 1.1 request, the response is chunk encoded. If it were not, it would not contain the content-length, and you would need to read the entire body.

The copy request charge is based on the storage class and Region that you specify for the destination object. For pricing information, see Amazon S3 pricing.

Amazon S3 transfer acceleration does not support cross-Region copies. If you request a cross-Region copy using a transfer acceleration endpoint, you get a 400

Bad
                                                                                      Request

error. For more information, see Transfer Acceleration.

Metadata

When copying an object, you can preserve all metadata (default) or specify new metadata. However, the ACL is not preserved and is set to private for the user making the request. To override the default ACL setting, specify a new ACL when generating a copy request. For more information, see Using ACLs.

To specify whether you want the object metadata copied from the source object or replaced with metadata provided in the request, you can optionally add the

x-amz-metadata-directive

header. When you grant permissions, you can use the

s3:x-amz-metadata-directive

condition key to enforce certain metadata behavior when objects are uploaded. For more information, see Specifying Conditions in a Policy in the Amazon S3 User Guide. For a complete list of Amazon S3-specific condition keys, see Actions, Resources, and Condition Keys for Amazon S3.

note

x-amz-website-redirect-location

is unique to each object and must be specified in the request headers to copy the value.

x-amz-copy-source-if Headers

To only copy an object under certain conditions, such as whether the

Etag

matches or whether the object was modified before or after a specified date, use the following request parameters:

• x-amz-copy-source-if-match

• x-amz-copy-source-if-none-match

• x-amz-copy-source-if-unmodified-since

• x-amz-copy-source-if-modified-since

If both the

x-amz-copy-source-if-match

and

x-amz-copy-source-if-unmodified-since

headers are present in the request and evaluate as follows, Amazon S3 returns

200
                                                                                          OK

and copies the data:

• x-amz-copy-source-if-match

  condition evaluates to true

• x-amz-copy-source-if-unmodified-since

  condition evaluates to false

If both the

x-amz-copy-source-if-none-match

and

x-amz-copy-source-if-modified-since

headers are present in the request and evaluate as follows, Amazon S3 returns the

412 Precondition Failed

response code:

• x-amz-copy-source-if-none-match

  condition evaluates to false

• x-amz-copy-source-if-modified-since

  condition evaluates to true

note

All headers with the

x-amz-

prefix, including

x-amz-copy-source

, must be signed.

Server-side encryption

Amazon S3 automatically encrypts all new objects that are copied to an S3 bucket. When copying an object, if you don't specify encryption information in your copy request, the encryption setting of the target object is set to the default encryption configuration of the destination bucket. By default, all buckets have a base level of encryption configuration that uses server-side encryption with Amazon S3 managed keys (SSE-S3). If the destination bucket has a default encryption configuration that uses server-side encryption with an Key Management Service (KMS) key (SSE-KMS), or a customer-provided encryption key (SSE-C), Amazon S3 uses the corresponding KMS key, or a customer-provided key to encrypt the target object copy. When you perform a CopyObject operation, if you want to use a different type of encryption setting for the target object, you can use other appropriate encryption-related headers to encrypt the target object with a KMS key, an Amazon S3 managed key, or a customer-provided key. With server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts the data when you access it. If the encryption setting in your request is different from the default encryption configuration of the destination bucket, the encryption setting in your request takes precedence. If the source object for the copy is stored in Amazon S3 using SSE-C, you must provide the necessary encryption information in your request so that Amazon S3 can decrypt the object for copying. For more information about server-side encryption, see Using Server-Side Encryption.

If a target object uses SSE-KMS, you can enable an S3 Bucket Key for the object. For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide.

Access Control List (ACL)-Specific Request Headers

When copying an object, you can optionally use headers to grant ACL-based permissions. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API.

If the bucket that you're copying objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don't specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the

bucket-owner-full-control

canned ACL or an equivalent form of this ACL expressed in the XML format.

For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide.

note

If your bucket uses the bucket owner enforced setting for Object Ownership, all objects written to the bucket by any account will be owned by the bucket owner.

Checksums

When copying an object, if it has a checksum, that checksum will be copied to the new object by default. When you copy the object over, you may optionally specify a different checksum algorithm to use with the

x-amz-checksum-algorithm

header.

Storage Class Options

You can use the

CopyObject

action to change the storage class of an object that is already stored in Amazon S3 using the

StorageClass

parameter. For more information, see Storage Classes in the Amazon S3 User Guide.

Versioning

By default,

x-amz-copy-source

identifies the current version of an object to copy. If the current version is a delete marker, Amazon S3 behaves as if the object was deleted. To copy a different version, use the

versionId

subresource.

If you enable versioning on the target bucket, Amazon S3 generates a unique version ID for the object being copied. This version ID is different from the version ID of the source object. Amazon S3 returns the version ID of the copied object in the

x-amz-version-id

response header in the response.

If you do not enable versioning or suspend it on the target bucket, the version ID that Amazon S3 generates is always null.

If the source object's storage class is GLACIER, you must restore a copy of this object before you can use it as a source object for the copy operation. For more information, see RestoreObject.

DeleteBucketIntelligentTieringConfigurationAsync(DeleteBucketIntelligentTieringConfigurationRequest, CancellationToken)

Deletes the S3 Intelligent-Tiering configuration from the specified bucket.

The S3 Intelligent-Tiering storage class is designed to optimize storage costs by automatically moving data to the most cost-effective storage access tier, without performance impact or operational overhead. S3 Intelligent-Tiering delivers automatic cost savings in three low latency and high throughput access tiers. To get the lowest storage cost on data that can be accessed in minutes to hours, you can choose to activate additional archiving capabilities.

The S3 Intelligent-Tiering storage class is the ideal storage class for data with unknown, changing, or unpredictable access patterns, independent of object size or retention period. If the size of an object is less than 128 KB, it is not monitored and not eligible for auto-tiering. Smaller objects can be stored, but they are always charged at the Frequent Access tier rates in the S3 Intelligent-Tiering storage class.

For more information, see Storage class for automatically optimizing frequently and infrequently accessed objects.

DeleteObjectAsync(DeleteObjectRequest, CancellationToken)

Removes the null version (if there is one) of an object and inserts a delete marker, which becomes the latest version of the object. If there isn't a null version, Amazon S3 does not remove any objects but will still respond that the command was successful.

To remove a specific version, you must use the version Id subresource. Using this subresource permanently deletes the version. If the object deleted is a delete marker, Amazon S3 sets the response header,

x-amz-delete-marker

, to true.

If the object you want to delete is in a bucket where the bucket versioning configuration is MFA Delete enabled, you must include the

x-amz-mfa

request header in the DELETE

versionId

request. Requests that include

x-amz-mfa

must use HTTPS.

For more information about MFA Delete, see Using MFA Delete. To see sample requests that use versioning, see Sample Request.

You can delete objects by explicitly calling DELETE Object or configure its lifecycle (PutBucketLifecycle) to enable Amazon S3 to remove them for you. If you want to block users or accounts from removing or deleting objects from your bucket, you must deny them the

s3:DeleteObject

,

s3:DeleteObjectVersion

, and

s3:PutLifeCycleConfiguration

DeleteObjectsAsync(DeleteObjectsRequest, CancellationToken)

This action enables you to delete multiple objects from a bucket using a single HTTP request. If you know the object keys that you want to delete, then this action provides a suitable alternative to sending individual delete requests, reducing per-request overhead.

The request contains a list of up to 1000 keys that you want to delete. In the XML, you provide the object key names, and optionally, version IDs if you want to delete a specific version of the object from a versioning-enabled bucket. For each key, Amazon S3 performs a delete action and returns the result of that delete, success, or failure, in the response. Note that if the object specified in the request is not found, Amazon S3 returns the result as deleted.

The action supports two modes for the response: verbose and quiet. By default, the action uses verbose mode in which the response includes the result of deletion of each key in your request. In quiet mode the response includes only keys where the delete action encountered an error. For a successful deletion, the action does not return any information about the delete in the response body.

When performing this action on an MFA Delete enabled bucket, that attempts to delete any versioned objects, you must include an MFA token. If you do not provide one, the entire request will fail, even if there are non-versioned objects you are trying to delete. If you provide an invalid token, whether there are versioned keys in the request or not, the entire Multi-Object Delete request will fail. For information about MFA Delete, see MFA Delete.

Finally, the Content-MD5 header is required for all Multi-Object Delete requests. Amazon S3 uses the header value to ensure that your request body has not been altered in transit.

GetBucketIntelligentTieringConfigurationAsync(GetBucketIntelligentTieringConfigurationRequest, CancellationToken)

Gets the S3 Intelligent-Tiering configuration from the specified bucket.

The S3 Intelligent-Tiering storage class is designed to optimize storage costs by automatically moving data to the most cost-effective storage access tier, without performance impact or operational overhead. S3 Intelligent-Tiering delivers automatic cost savings in three low latency and high throughput access tiers. To get the lowest storage cost on data that can be accessed in minutes to hours, you can choose to activate additional archiving capabilities.

The S3 Intelligent-Tiering storage class is the ideal storage class for data with unknown, changing, or unpredictable access patterns, independent of object size or retention period. If the size of an object is less than 128 KB, it is not monitored and not eligible for auto-tiering. Smaller objects can be stored, but they are always charged at the Frequent Access tier rates in the S3 Intelligent-Tiering storage class.

For more information, see Storage class for automatically optimizing frequently and infrequently accessed objects.

GetObjectAsync(GetObjectRequest, CancellationToken)

Retrieves objects from Amazon S3. To use

GET

, you must have

READ

access to the object. If you grant

READ

access to the anonymous user, you can return the object without using an authorization header.

An Amazon S3 bucket has no directory hierarchy such as you would find in a typical computer file system. You can, however, create a logical hierarchy by using object key names that imply a folder structure. For example, instead of naming an object

sample.jpg

, you can name it

photos/2006/February/sample.jpg

.

To get an object from such a logical hierarchy, specify the full key name for the object in the

GET

operation. For a virtual hosted-style request example, if you have the object

photos/2006/February/sample.jpg

, specify the resource as

/photos/2006/February/sample.jpg

. For a path-style request example, if you have the object

photos/2006/February/sample.jpg

in the bucket named

examplebucket

, specify the resource as

/examplebucket/photos/2006/February/sample.jpg

. For more information about request types, see HTTP Host Header Bucket Specification.

For more information about returning the ACL of an object, see GetObjectAcl.

If the object you are retrieving is stored in the S3 Glacier or S3 Glacier Deep Archive storage class, or S3 Intelligent-Tiering Archive or S3 Intelligent-Tiering Deep Archive tiers, before you can retrieve the object you must first restore a copy using RestoreObject. Otherwise, this action returns an

InvalidObjectState

error. For information about restoring archived objects, see Restoring Archived Objects.

Encryption request headers, like

x-amz-server-side-encryption

, should not be sent for GET requests if your object uses server-side encryption with KMS keys (SSE-KMS) or server-side encryption with Amazon S3–managed encryption keys (SSE-S3). If your object does use these types of keys, you’ll get an HTTP 400 BadRequest error.

If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you GET the object, you must use the following headers:

• x-amz-server-side-encryption-customer-algorithm

• x-amz-server-side-encryption-customer-key

• x-amz-server-side-encryption-customer-key-MD5

For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys).

Assuming you have the relevant permission to read object tags, the response also returns the

x-amz-tagging-count

header that provides the count of number of tags associated with the object. You can use GetObjectTagging to retrieve the tag set associated with an object.

Permissions

You need the relevant read object (or version) permission for this operation. For more information, see Specifying Permissions in a Policy. If the object you request does not exist, the error Amazon S3 returns depends on whether you also have the

s3:ListBucket

permission.

• If you have the

  s3:ListBucket

  permission on the bucket, Amazon S3 will return an HTTP status code 404 ("no such key") error.

• If you don’t have the

  s3:ListBucket

  permission, Amazon S3 will return an HTTP status code 403 ("access denied") error.

Versioning

By default, the GET action returns the current version of an object. To return a different version, use the

versionId

subresource.

note

• If you supply a

  versionId

  , you need the

  s3:GetObjectVersion

  permission to access a specific version of an object. If you request a specific version, you do not need to have the

  s3:GetObject

  permission. If you request the current version without a specific version ID, only

  s3:GetObject

  permission is required.

  s3:GetObjectVersion

  permission won't be required.

• If the current version of the object is a delete marker, Amazon S3 behaves as if the object was deleted and includes

  x-amz-delete-marker: true

  in the response.

For more information about versioning, see PutBucketVersioning.

Overriding Response Header Values

There are times when you want to override certain response header values in a GET response. For example, you might override the

Content-Disposition

response header value in your GET request.

You can override values for a set of response headers using the following query parameters. These response header values are sent only on a successful request, that is, when status code 200 OK is returned. The set of headers you can override using these parameters is a subset of the headers that Amazon S3 accepts when you create an object. The response headers that you can override for the GET response are

Content-Type

,

Content-Language

,

Expires

,

Cache-Control

,

Content-Disposition

, and

Content-Encoding

. To override these header values in the GET response, you use the following request parameters.

note

You must sign the request, either using an Authorization header or a presigned URL, when using these parameters. They cannot be used with an unsigned (anonymous) request.

• response-content-type

• response-content-language

• response-expires

• response-cache-control

• response-content-disposition

• response-content-encoding

Additional Considerations about Request Headers

If both of the

If-Match

and

If-Unmodified-Since

headers are present in the request as follows:

If-Match

condition evaluates to

true

, and;

If-Unmodified-Since

condition evaluates to

false

; then, S3 returns 200 OK and the data requested.

If both of the

If-None-Match

and

If-Modified-Since

headers are present in the request as follows:

If-None-Match

condition evaluates to

false

, and;

If-Modified-Since

condition evaluates to

true

; then, S3 returns 304 Not Modified response code.

For more information about conditional requests, see RFC 7232.

The following operations are related to

GetObject

:

• ListBuckets

• GetObjectAcl

public virtual Task<GetObjectResponse> GetObjectAsync(string bucketName, string key, CancellationToken cancellationToken = default)

Parameters

bucketName string

The bucket name containing the object. When using this action with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.Region.amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide. When using an Object Lambda access point the hostname takes the form AccessPointName-AccountId.s3-object-lambda.Region.amazonaws.com. When you use this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form

AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com

. When you use this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts in the Amazon S3 User Guide.

key string

Key of the object to get.

cancellationToken CancellationToken

A cancellation token that can be used by other objects or threads to receive notice of cancellation.

Returns

Task<GetObjectResponse>

The response from the GetObject service method, as returned by S3.

See Also

REST API Reference for GetObject Operation

GetObjectAttributesAsync(GetObjectAttributesRequest, CancellationToken)

Retrieves all the metadata from an object without returning the object itself. This action is useful if you're interested only in an object's metadata. To use

GetObjectAttributes

, you must have READ access to the object.

GetObjectAttributes

combines the functionality of

HeadObject

and

ListParts

. All of the data returned with each of those individual calls can be returned with a single call to

GetObjectAttributes

.

If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you retrieve the metadata from the object, you must use the following headers:

• x-amz-server-side-encryption-customer-algorithm

• x-amz-server-side-encryption-customer-key

• x-amz-server-side-encryption-customer-key-MD5

For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) in the Amazon S3 User Guide.

note

• Encryption request headers, such as

  x-amz-server-side-encryption

  , should not be sent for GET requests if your object uses server-side encryption with Amazon Web Services KMS keys stored in Amazon Web Services Key Management Service (SSE-KMS) or server-side encryption with Amazon S3 managed keys (SSE-S3). If your object does use these types of keys, you'll get an HTTP

  400 Bad Request

  error.

• The last modified property in this case is the creation date of the object.

Consider the following when using request headers:

• If both of the

  If-Match

  and

  If-Unmodified-Since

  headers are present in the request as follows, then Amazon S3 returns the HTTP status code

  200 OK

  and the data requested:

  • If-Match

    condition evaluates to

    true

    .

  • If-Unmodified-Since

    condition evaluates to

    false

    .

• If both of the

  If-None-Match

  and

  If-Modified-Since

  headers are present in the request as follows, then Amazon S3 returns the HTTP status code

  304 Not Modified

  :

  • If-None-Match

    condition evaluates to

    false

    .

  • If-Modified-Since

    condition evaluates to

    true

    .

For more information about conditional requests, see RFC 7232.

Permissions

The permissions that you need to use this operation depend on whether the bucket is versioned. If the bucket is versioned, you need both the

s3:GetObjectVersion

and

s3:GetObjectVersionAttributes

permissions for this operation. If the bucket is not versioned, you need the

s3:GetObject

and

s3:GetObjectAttributes

permissions. For more information, see Specifying Permissions in a Policy in the Amazon S3 User Guide. If the object that you request does not exist, the error Amazon S3 returns depends on whether you also have the

s3:ListBucket

permission.

• If you have the

  s3:ListBucket

  permission on the bucket, Amazon S3 returns an HTTP status code

  404 Not Found

  ("no such key") error.

• If you don't have the

  s3:ListBucket

  permission, Amazon S3 returns an HTTP status code

  403 Forbidden

  ("access denied") error.

GetObjectMetadataAsync(GetObjectMetadataRequest, CancellationToken)

The HEAD action retrieves metadata from an object without returning the object itself. This action is useful if you're only interested in an object's metadata. To use HEAD, you must have READ access to the object.

A

HEAD

request has the same options as a

GET

action on an object. The response is identical to the

GET

response except that there is no response body. Because of this, if the

HEAD

request generates an error, it returns a generic

400 Bad Request

,

403 Forbidden

or

404 Not Found

code. It is not possible to retrieve the exact exception beyond these error codes.

If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you retrieve the metadata from the object, you must use the following headers:

• x-amz-server-side-encryption-customer-algorithm

• x-amz-server-side-encryption-customer-key

• x-amz-server-side-encryption-customer-key-MD5

For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys).

note

• Encryption request headers, like

  x-amz-server-side-encryption

  , should not be sent for GET requests if your object uses server-side encryption with KMS keys (SSE-KMS) or server-side encryption with Amazon S3–managed encryption keys (SSE-S3). If your object does use these types of keys, you’ll get an HTTP 400 BadRequest error.

• The last modified property in this case is the creation date of the object.

Request headers are limited to 8 KB in size. For more information, see Common Request Headers.

Consider the following when using request headers:

• Consideration 1 – If both of the

  If-Match

  and

  If-Unmodified-Since

  headers are present in the request as follows:

  • If-Match

    condition evaluates to

GetPublicAccessBlockAsync(GetPublicAccessBlockRequest, CancellationToken)

Retrieves the

PublicAccessBlock

configuration for an Amazon S3 bucket. To use this operation, you must have the

s3:GetBucketPublicAccessBlock

permission. For more information about Amazon S3 permissions, see Specifying Permissions in a Policy.

When Amazon S3 evaluates the

PublicAccessBlock

configuration for a bucket or an object, it checks the

PublicAccessBlock

configuration for both the bucket (or the bucket that contains the object) and the bucket owner's account. If the

PublicAccessBlock

settings are different between the bucket and the account, Amazon S3 uses the most restrictive combination of the bucket-level and account-level settings.

For more information about when Amazon S3 considers a bucket or an object public, see The Meaning of "Public".

The following operations are related to

GetPublicAccessBlock

:

• Using Amazon S3 Block Public Access

• PutPublicAccessBlock

• GetPublicAccessBlock

• DeletePublicAccessBlock

public virtual Task<GetPublicAccessBlockResponse> GetPublicAccessBlockAsync(GetPublicAccessBlockRequest request, CancellationToken cancellationToken = default)

REST API Reference for GetPublicAccessBlock Operation

Initialize()

Specialize the initialize of the client.

protected override void Initialize()

InitiateMultipartUploadAsync(InitiateMultipartUploadRequest, CancellationToken)

This action initiates a multipart upload and returns an upload ID. This upload ID is used to associate all of the parts in the specific multipart upload. You specify this upload ID in each of your subsequent upload part requests (see UploadPart). You also include this upload ID in the final request to either complete or abort the multipart upload request.

For more information about multipart uploads, see Multipart Upload Overview.

If you have configured a lifecycle rule to abort incomplete multipart uploads, the upload must complete within the number of days specified in the bucket lifecycle configuration. Otherwise, the incomplete multipart upload becomes eligible for an abort action and Amazon S3 aborts the multipart upload. For more information, see Aborting Incomplete Multipart Uploads Using a Bucket Lifecycle Policy.

For information about the permissions required to use the multipart upload API, see Multipart Upload and Permissions.

For request signing, multipart upload is just a series of regular requests. You initiate a multipart upload, send one or more requests to upload parts, and then complete the multipart upload process. You sign each request individually. There is nothing special about signing multipart upload requests. For more information about signing, see Authenticating Requests (Amazon Web Services Signature Version 4).

note

After you initiate a multipart upload and upload one or more parts, to stop being charged for storing the uploaded parts, you must either complete or abort the multipart upload. Amazon S3 frees up the space used to store the parts and stop charging you for storing them only after you either complete or abort a multipart upload.

Server-side encryption is for data encryption at rest. Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. Amazon S3 automatically encrypts all new objects that are uploaded to an S3 bucket. When doing a multipart upload, if you don't specify encryption information in your request, the encryption setting of the uploaded parts is set to the default encryption configuration of the destination bucket. By default, all buckets have a base level of encryption configuration that uses server-side encryption with Amazon S3 managed keys (SSE-S3). If the destination bucket has a default encryption configuration that uses server-side encryption with an Key Management Service (KMS) key (SSE-KMS), or a customer-provided encryption key (SSE-C), Amazon S3 uses the corresponding KMS key, or a customer-provided key to encrypt the uploaded parts. When you perform a CreateMultipartUpload operation, if you want to use a different type of encryption setting for the uploaded parts, you can request that Amazon S3 encrypts the object with a KMS key, an Amazon S3 managed key, or a customer-provided key. If the encryption setting in your request is different from the default encryption configuration of the destination bucket, the encryption setting in your request takes precedence. If you choose to provide your own encryption key, the request headers you provide in UploadPart and UploadPartCopy requests must match the headers you used in the request to initiate the upload by using

CreateMultipartUpload

. you can request that Amazon S3 save the uploaded parts encrypted with server-side encryption with an Amazon S3 managed key (SSE-S3), an Key Management Service (KMS) key (SSE-KMS), or a customer-provided encryption key (SSE-C).

To perform a multipart upload with encryption by using an Amazon Web Services KMS key, the requester must have permission to the

kms:Decrypt

and

kms:GenerateDataKey*

actions on the key. These permissions are required because Amazon S3 must decrypt and read data from the encrypted file parts before it completes the multipart upload. For more information, see Multipart upload API and permissions and Protecting data using server-side encryption with Amazon Web Services KMS in the Amazon S3 User Guide.

If your Identity and Access Management (IAM) user or role is in the same Amazon Web Services account as the KMS key, then you must have these permissions on the key policy. If your IAM user or role belongs to a different account than the key, then you must have the permissions on both the key policy and your IAM user or role.

For more information, see Protecting Data Using Server-Side Encryption.

Access Permissions

When copying an object, you can optionally specify the accounts or groups that should be granted specific permissions on the new object. There are two ways to grant the permissions using the request headers:

• Specify a canned ACL with the

  x-amz-acl

  request header. For more information, see Canned ACL.

• Specify access permissions explicitly with the

  x-amz-grant-read

  ,

  x-amz-grant-read-acp

  ,

  x-amz-grant-write-acp

  , and

  x-amz-grant-full-control

  headers. These parameters map to the set of permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview.

You can use either a canned ACL or specify access permissions explicitly. You cannot do both.

Server-Side- Encryption-Specific Request Headers

Amazon S3 encrypts data by using server-side encryption with an Amazon S3 managed key (SSE-S3) by default. Server-side encryption is for data encryption at rest. Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. You can request that Amazon S3 encrypts data at rest by using server-side encryption with other key options. The option you use depends on whether you want to use KMS keys (SSE-KMS) or provide your own encryption keys (SSE-C).

• Use KMS keys (SSE-KMS) that include the Amazon Web Services managed key (

  aws/s3

  ) and KMS customer managed keys stored in Key Management Service (KMS) – If you want Amazon Web Services to manage the keys used to encrypt data, specify the following headers in the request.

  • x-amz-server-side-encryption

  • x-amz-server-side-encryption-aws-kms-key-id

  • x-amz-server-side-encryption-context

  note

  If you specify

  x-amz-server-side-encryption:aws:kms

  , but don't provide

  x-amz-server-side-encryption-aws-kms-key-id

  , Amazon S3 uses the Amazon Web Services managed key (

  aws/s3

  key) in KMS to protect the data.

  All

  GET

  and

  PUT

  requests for an object protected by KMS fail if you don't make them by using Secure Sockets Layer (SSL), Transport Layer Security (TLS), or Signature Version 4.

  For more information about server-side encryption with KMS keys (SSE-KMS), see Protecting Data Using Server-Side Encryption with KMS keys.

• Use customer-provided encryption keys (SSE-C) – If you want to manage your own encryption keys, provide all the following headers in the request.

  • x-amz-server-side-encryption-customer-algorithm

  • x-amz-server-side-encryption-customer-key

  • x-amz-server-side-encryption-customer-key-MD5

  For more information about server-side encryption with customer-provided encryption keys (SSE-C), see Protecting data using server-side encryption with customer-provided encryption keys (SSE-C).

Access-Control-List (ACL)-Specific Request Headers

You also can use the following access control–related headers with this operation. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the access control list (ACL) on the object. For more information, see Using ACLs. With this operation, you can grant access permissions using one of the following two methods:

• Specify a canned ACL (

  x-amz-acl

  ) — Amazon S3 supports a set of predefined ACLs, known as canned ACLs. Each canned ACL has a predefined set of grantees and permissions. For more information, see Canned ACL.

• Specify access permissions explicitly — To explicitly grant access permissions to specific Amazon Web Services accounts or groups, use the following headers. Each header maps to specific permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview. In the header, you specify a list of grantees who get the specific permission. To grant permissions explicitly, use:

  • x-amz-grant-read

  • x-amz-grant-write

  • x-amz-grant-read-acp

  • x-amz-grant-write-acp

  • x-amz-grant-full-control

  You specify each grantee as a type=value pair, where the type is one of the following:

  • id

    – if the value specified is the canonical user ID of an Amazon Web Services account

  • uri

    – if you are granting permissions to a predefined group

  • emailAddress

    – if the value specified is the email address of an Amazon Web Services account

    note

    Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

    • US East (N. Virginia)

    • US West (N. California)

    • US West (Oregon)

    • Asia Pacific (Singapore)

    • Asia Pacific (Sydney)

    • Asia Pacific (Tokyo)

    • Europe (Ireland)

    • South America (São Paulo)

    For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

  For example, the following

  x-amz-grant-read

  header grants the Amazon Web Services accounts identified by account IDs permissions to read object data and its metadata:

  x-amz-grant-read: id="11112222333", id="444455556666"

The following operations are related to

CreateMultipartUpload

:

• UploadPart

• CompleteMultipartUpload

• AbortMultipartUpload

• ListParts

• ListMultipartUploads

public virtual Task<InitiateMultipartUploadResponse> InitiateMultipartUploadAsync(InitiateMultipartUploadRequest request, CancellationToken cancellationToken = default)

Parameters

request InitiateMultipartUploadRequest

Container for the necessary parameters to execute the InitiateMultipartUpload service method.

cancellationToken CancellationToken

A cancellation token that can be used by other objects or threads to receive notice of cancellation.

Returns

Task<InitiateMultipartUploadResponse>

The response from the InitiateMultipartUpload service method, as returned by S3.

See Also

REST API Reference for InitiateMultipartUpload Operation

InitiateMultipartUploadAsync(string, string, CancellationToken)

This action initiates a multipart upload and returns an upload ID. This upload ID is used to associate all of the parts in the specific multipart upload. You specify this upload ID in each of your subsequent upload part requests (see UploadPart). You also include this upload ID in the final request to either complete or abort the multipart upload request.

For more information about multipart uploads, see Multipart Upload Overview.

If you have configured a lifecycle rule to abort incomplete multipart uploads, the upload must complete within the number of days specified in the bucket lifecycle configuration. Otherwise, the incomplete multipart upload becomes eligible for an abort action and Amazon S3 aborts the multipart upload. For more information, see Aborting Incomplete Multipart Uploads Using a Bucket Lifecycle Policy.

For information about the permissions required to use the multipart upload API, see Multipart Upload and Permissions.

For request signing, multipart upload is just a series of regular requests. You initiate a multipart upload, send one or more requests to upload parts, and then complete the multipart upload process. You sign each request individually. There is nothing special about signing multipart upload requests. For more information about signing, see Authenticating Requests (Amazon Web Services Signature Version 4).

note

After you initiate a multipart upload and upload one or more parts, to stop being charged for storing the uploaded parts, you must either complete or abort the multipart upload. Amazon S3 frees up the space used to store the parts and stop charging you for storing them only after you either complete or abort a multipart upload.

Server-side encryption is for data encryption at rest. Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. Amazon S3 automatically encrypts all new objects that are uploaded to an S3 bucket. When doing a multipart upload, if you don't specify encryption information in your request, the encryption setting of the uploaded parts is set to the default encryption configuration of the destination bucket. By default, all buckets have a base level of encryption configuration that uses server-side encryption with Amazon S3 managed keys (SSE-S3). If the destination bucket has a default encryption configuration that uses server-side encryption with an Key Management Service (KMS) key (SSE-KMS), or a customer-provided encryption key (SSE-C), Amazon S3 uses the corresponding KMS key, or a customer-provided key to encrypt the uploaded parts. When you perform a CreateMultipartUpload operation, if you want to use a different type of encryption setting for the uploaded parts, you can request that Amazon S3 encrypts the object with a KMS key, an Amazon S3 managed key, or a customer-provided key. If the encryption setting in your request is different from the default encryption configuration of the destination bucket, the encryption setting in your request takes precedence. If you choose to provide your own encryption key, the request headers you provide in UploadPart and UploadPartCopy requests must match the headers you used in the request to initiate the upload by using

CreateMultipartUpload

. you can request that Amazon S3 save the uploaded parts encrypted with server-side encryption with an Amazon S3 managed key (SSE-S3), an Key Management Service (KMS) key (SSE-KMS), or a customer-provided encryption key (SSE-C).

To perform a multipart upload with encryption by using an Amazon Web Services KMS key, the requester must have permission to the

kms:Decrypt

and

kms:GenerateDataKey*

actions on the key. These permissions are required because Amazon S3 must decrypt and read data from the encrypted file parts before it completes the multipart upload. For more information, see Multipart upload API and permissions and Protecting data using server-side encryption with Amazon Web Services KMS in the Amazon S3 User Guide.

If your Identity and Access Management (IAM) user or role is in the same Amazon Web Services account as the KMS key, then you must have these permissions on the key policy. If your IAM user or role belongs to a different account than the key, then you must have the permissions on both the key policy and your IAM user or role.

For more information, see Protecting Data Using Server-Side Encryption.

Access Permissions

When copying an object, you can optionally specify the accounts or groups that should be granted specific permissions on the new object. There are two ways to grant the permissions using the request headers:

• Specify a canned ACL with the

  x-amz-acl

  request header. For more information, see Canned ACL.

• Specify access permissions explicitly with the

  x-amz-grant-read

  ,

  x-amz-grant-read-acp

  ,

  x-amz-grant-write-acp

  , and

  x-amz-grant-full-control

  headers. These parameters map to the set of permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview.

You can use either a canned ACL or specify access permissions explicitly. You cannot do both.

  • x-amz-server-side-encryption

  • x-amz-server-side-encryption-aws-kms-key-id

  • x-amz-server-side-encryption-context

  note

  If you specify

  x-amz-server-side-encryption:aws:kms

  , but don't provide

  x-amz-server-side-encryption-aws-kms-key-id

  , Amazon S3 uses the Amazon Web Services managed key (

  All

  GET

  and

  PUT

  requests for an object protected by KMS fail if you don't make them by using Secure Sockets Layer (SSL), Transport Layer Security (TLS), or Signature Version 4.

  For more information about server-side encryption with KMS keys (SSE-KMS), see Protecting Data Using Server-Side Encryption with KMS keys.

• Use customer-provided encryption keys (SSE-C) – If you want to manage your own encryption keys, provide all the following headers in the request.

  • x-amz-server-side-encryption-customer-algorithm

  • x-amz-server-side-encryption-customer-key

  • x-amz-server-side-encryption-customer-key-MD5

  • x-amz-grant-read

  • x-amz-grant-write

  • x-amz-grant-read-acp

  • x-amz-grant-write-acp

  • x-amz-grant-full-control

  You specify each grantee as a type=value pair, where the type is one of the following:

  • id

    – if the value specified is the canonical user ID of an Amazon Web Services account

  • uri

    – if you are granting permissions to a predefined group

  • emailAddress

    – if the value specified is the email address of an Amazon Web Services account

    note

    Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

    • US East (N. Virginia)

    • US West (N. California)

    • US West (Oregon)

    • Asia Pacific (Singapore)

ListBucketIntelligentTieringConfigurationsAsync(ListBucketIntelligentTieringConfigurationsRequest, CancellationToken)

Lists the S3 Intelligent-Tiering configuration from the specified bucket.

The S3 Intelligent-Tiering storage class is designed to optimize storage costs by automatically moving data to the most cost-effective storage access tier, without performance impact or operational overhead. S3 Intelligent-Tiering delivers automatic cost savings in three low latency and high throughput access tiers. To get the lowest storage cost on data that can be accessed in minutes to hours, you can choose to activate additional archiving capabilities.

The S3 Intelligent-Tiering storage class is the ideal storage class for data with unknown, changing, or unpredictable access patterns, independent of object size or retention period. If the size of an object is less than 128 KB, it is not monitored and not eligible for auto-tiering. Smaller objects can be stored, but they are always charged at the Frequent Access tier rates in the S3 Intelligent-Tiering storage class.

Returns

Task<PutACLResponse>

PutBucketAccelerateConfigurationAsync(PutBucketAccelerateConfigurationRequest, CancellationToken)

Sets the accelerate configuration of an existing bucket. Amazon S3 Transfer Acceleration is a bucket-level feature that enables you to perform faster data transfers to Amazon S3.

To use this operation, you must have permission to perform the

s3:PutAccelerateConfiguration

action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources.

The Transfer Acceleration state of a bucket can be set to one of the following two values:

• Enabled – Enables accelerated data transfers to the bucket.

• Suspended – Disables accelerated data transfers to the bucket.

The GetBucketAccelerateConfiguration action returns the transfer acceleration state of a bucket.

After setting the Transfer Acceleration state of a bucket to Enabled, it might take up to thirty minutes before the data transfer rates to the bucket increase.

The name of the bucket used for Transfer Acceleration must be DNS-compliant and must not contain periods (".").

For more information about transfer acceleration, see Transfer Acceleration.

PutBucketAnalyticsConfigurationAsync(PutBucketAnalyticsConfigurationRequest, CancellationToken)

public virtual Task<PutBucketAnalyticsConfigurationResponse> PutBucketAnalyticsConfigurationAsync(PutBucketAnalyticsConfigurationRequest request, CancellationToken cancellationToken = default)

Parameters

request PutBucketAnalyticsConfigurationRequest

cancellationToken CancellationToken

Returns

Task<PutBucketAnalyticsConfigurationResponse>

PutBucketAsync(PutBucketRequest, CancellationToken)

Creates a new S3 bucket. To create a bucket, you must register with Amazon S3 and have a valid Amazon Web Services Access Key ID to authenticate requests. Anonymous requests are never allowed to create buckets. By creating the bucket, you become the bucket owner.

Not every string is an acceptable bucket name. For information about bucket naming restrictions, see Bucket naming rules.

If you want to create an Amazon S3 on Outposts bucket, see Create Bucket.

By default, the bucket is created in the US East (N. Virginia) Region. You can optionally specify a Region in the request body. You might choose a Region to optimize latency, minimize costs, or address regulatory requirements. For example, if you reside in Europe, you will probably find it advantageous to create buckets in the Europe (Ireland) Region. For more information, see Accessing a bucket.

note

If you send your create bucket request to the

s3.amazonaws.com

endpoint, the request goes to the us-east-1 Region. Accordingly, the signature calculations in Signature Version 4 must use us-east-1 as the Region, even if the location constraint in the request specifies another Region where the bucket is to be created. If you create a bucket in a Region other than US East (N. Virginia), your application must be able to handle 307 redirect. For more information, see Virtual hosting of buckets.

Access control lists (ACLs)

When creating a bucket using this operation, you can optionally configure the bucket ACL to specify the accounts or groups that should be granted specific permissions on the bucket.

If your CreateBucket request sets bucket owner enforced for S3 Object Ownership and specifies a bucket ACL that provides access to an external Amazon Web Services account, your request fails with a

400

error and returns the

InvalidBucketAclWithObjectOwnership

error code. For more information, see Controlling object ownership in the Amazon S3 User Guide.

There are two ways to grant the appropriate permissions using the request headers.

• Specify a canned ACL using the

  x-amz-acl

  request header. Amazon S3 supports a set of predefined ACLs, known as canned ACLs. Each canned ACL has a predefined set of grantees and permissions. For more information, see Canned ACL.

• Specify access permissions explicitly using the

  x-amz-grant-read

  ,

  x-amz-grant-write

  ,

  x-amz-grant-read-acp

  ,

  x-amz-grant-write-acp

  , and

  x-amz-grant-full-control

  headers. These headers map to the set of permissions Amazon S3 supports in an ACL. For more information, see Access control list (ACL) overview.

  You specify each grantee as a type=value pair, where the type is one of the following:

  • id

    – if the value specified is the canonical user ID of an Amazon Web Services account

  • uri

    – if you are granting permissions to a predefined group

  • emailAddress

    – if the value specified is the email address of an Amazon Web Services account

    note

    Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

    • US East (N. Virginia)

    • US West (N. California)

    • US West (Oregon)

    • Asia Pacific (Singapore)

    • Asia Pacific (Sydney)

    • Asia Pacific (Tokyo)

    • Europe (Ireland)

    • South America (São Paulo)

    For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

  For example, the following

  x-amz-grant-read

  header grants the Amazon Web Services accounts identified by account IDs permissions to read object data and its metadata:

  x-amz-grant-read: id="11112222333", id="444455556666"

note

You can use either a canned ACL or specify access permissions explicitly. You cannot do both.

Permissions

In addition to

s3:CreateBucket

, the following permissions are required when your CreateBucket includes specific headers:

• ACLs - If your

  CreateBucket

  request specifies ACL permissions and the ACL is public-read, public-read-write, authenticated-read, or if you specify access permissions explicitly through any other ACL, both

  s3:CreateBucket

  and

  s3:PutBucketAcl

  permissions are needed. If the ACL the

  CreateBucket

  request is private or doesn't specify any ACLs, only

  s3:CreateBucket

  permission is needed.

• Object Lock - If

  ObjectLockEnabledForBucket

  is set to true in your

  CreateBucket

  request,

  s3:PutBucketObjectLockConfiguration

  and

  s3:PutBucketVersioning

  permissions are required.

• S3 Object Ownership - If your CreateBucket request includes the the

  x-amz-object-ownership

  header,

  s3:PutBucketOwnershipControls

  permission is required.

PutBucketNotificationAsync(PutBucketNotificationRequest, CancellationToken)

Enables notifications of specified events for a bucket. For more information about event notifications, see Configuring Event Notifications.

Using this API, you can replace an existing notification configuration. The configuration is an XML file that defines the event types that you want Amazon S3 to publish and the destination where you want Amazon S3 to publish an event notification when it detects an event of the specified type.

By default, your bucket has no event notifications configured. That is, the notification configuration will be an empty

NotificationConfiguration

.

<NotificationConfiguration>

</NotificationConfiguration>

This action replaces the existing notification configuration with the configuration you include in the request body.

After Amazon S3 receives this request, it first verifies that any Amazon Simple Notification Service (Amazon SNS) or Amazon Simple Queue Service (Amazon SQS) destination exists, and that the bucket owner has permission to publish to it by sending a test notification. In the case of Lambda destinations, Amazon S3 verifies that the Lambda function permissions grant Amazon S3 permission to invoke the function from the Amazon S3 bucket. For more information, see Configuring Notifications for Amazon S3 Events.

You can disable notifications by adding the empty NotificationConfiguration element.

For more information about the number of event notification configurations that you can create per bucket, see Amazon S3 service quotas in Amazon Web Services General Reference.

By default, only the bucket owner can configure notifications on a bucket. However, bucket owners can use a bucket policy to grant permission to other users to set this configuration with

s3:PutBucketNotification

permission.

note

The PUT notification is an atomic operation. For example, suppose your notification configuration includes SNS topic, SQS queue, and Lambda function configurations. When you send a PUT request with this configuration, Amazon S3 sends test messages to your SNS topic. If the message fails, the entire PUT action will fail, and Amazon S3 will not add the configuration to your bucket.

Responses

If the configuration in the request body includes only one

TopicConfiguration

specifying only the

s3:ReducedRedundancyLostObject

event type, the response will also include the

x-amz-sns-test-message-id

header containing the message ID of the test notification sent to the topic.

The following action is related to

PutBucketNotificationConfiguration

:

• GetBucketNotificationConfiguration

public virtual Task<PutBucketNotificationResponse> PutBucketNotificationAsync(PutBucketNotificationRequest request, CancellationToken cancellationToken = default)

PutBucketReplicationAsync(PutBucketReplicationRequest, CancellationToken)

Creates a replication configuration or replaces an existing one. For more information, see Replication in the Amazon S3 User Guide.

Specify the replication configuration in the request body. In the replication configuration, you provide the name of the destination bucket or buckets where you want Amazon S3 to replicate objects, the IAM role that Amazon S3 can assume to replicate objects on your behalf, and other relevant information.

A replication configuration must include at least one rule, and can contain a maximum of 1,000. Each rule identifies a subset of objects to replicate by filtering the objects in the source bucket. To choose additional subsets of objects to replicate, add a rule for each subset.

To specify a subset of the objects in the source bucket to apply a replication rule to, add the Filter element as a child of the Rule element. You can filter objects based on an object key prefix, one or more object tags, or both. When you add the Filter element in the configuration, you must also add the following elements:

DeleteMarkerReplication

,

Status

, and

Priority

.

note

If you are using an earlier version of the replication configuration, Amazon S3 handles replication of delete markers differently. For more information, see Backward Compatibility.

For information about enabling versioning on a bucket, see Using Versioning.

Handling Replication of Encrypted Objects

By default, Amazon S3 doesn't replicate objects that are stored at rest using server-side encryption with KMS keys. To replicate Amazon Web Services KMS-encrypted objects, add the following:

SourceSelectionCriteria

,

SseKmsEncryptedObjects

,

Status

,

EncryptionConfiguration

, and

ReplicaKmsKeyID

. For information about replication configuration, see Replicating Objects Created with SSE Using KMS keys.

For information on

PutBucketReplication

errors, see List of replication-related error codes

• WebsiteConfiguration

• RedirectAllRequestsTo

• HostName

• Protocol

If you want granular control over redirects, you can use the following elements to add routing rules that describe conditions for redirecting requests and information about the redirect destination. In this case, the website configuration must provide an index document for the bucket, because some requests might not be redirected.

• WebsiteConfiguration

• IndexDocument

• Suffix

• ErrorDocument

• Key

• RoutingRules

• RoutingRule

• Condition

• HttpErrorCodeReturnedEquals

• KeyPrefixEquals

• Redirect

• Protocol

cancellationToken CancellationToken

Returns

Task<PutCORSConfigurationResponse>

PutLifecycleConfigurationAsync(PutLifecycleConfigurationRequest, CancellationToken)

Creates a new lifecycle configuration for the bucket or replaces an existing lifecycle configuration. Keep in mind that this will overwrite an existing lifecycle configuration, so if you want to retain any configuration details, they must be included in the new lifecycle configuration. For information about lifecycle configuration, see Managing your storage lifecycle.

note

Bucket lifecycle configuration now supports specifying a lifecycle rule using an object key name prefix, one or more object tags, or a combination of both. Accordingly, this section describes the latest API. The previous version of the API supported filtering based only on an object key name prefix, which is supported for backward compatibility. For the related API description, see PutBucketLifecycle.

Rules

You specify the lifecycle configuration in your request body. The lifecycle configuration is specified as XML consisting of one or more rules. An Amazon S3 Lifecycle configuration can have up to 1,000 rules. This limit is not adjustable. Each rule consists of the following:

• Filter identifying a subset of objects to which the rule applies. The filter can be based on a key name prefix, object tags, or a combination of both.

• Status whether the rule is in effect.

• One or more lifecycle transition and expiration actions that you want Amazon S3 to perform on the objects identified by the filter. If the state of your bucket is versioning-enabled or versioning-suspended, you can have many versions of the same object (one current version and zero or more noncurrent versions). Amazon S3 provides predefined actions that you can specify for current and noncurrent object versions.

For more information, see Object Lifecycle Management and Lifecycle Configuration Elements.

Permissions

By default, all Amazon S3 resources are private, including buckets, objects, and related subresources (for example, lifecycle configuration and website configuration). Only the resource owner (that is, the Amazon Web Services account that created it) can access the resource. The resource owner can optionally grant access permissions to others by writing an access policy. For this operation, a user must get the

s3:PutLifecycleConfiguration

permission.

You can also explicitly deny permissions. Explicit deny also supersedes any other permissions. If you want to block users or accounts from removing or deleting objects from your bucket, you must deny them permissions for the following actions:

• s3:DeleteObject

• s3:DeleteObjectVersion

• s3:PutLifecycleConfiguration

For more information about permissions, see Managing Access Permissions to Your Amazon S3 Resources.

• One or more lifecycle transition and expiration actions that you want Amazon S3 to perform on the objects identified by the filter. If the state of your bucket is versioning-enabled or versioning-suspended, you can have many versions of the same object (one current version and zero or more noncurrent versions). Amazon S3 provides predefined actions that you can specify for current and noncurrent object versions.

For more information, see Object Lifecycle Management and Lifecycle Configuration Elements.

Permissions

By default, all Amazon S3 resources are private, including buckets, objects, and related subresources (for example, lifecycle configuration and website configuration). Only the resource owner (that is, the Amazon Web Services account that created it) can access the resource. The resource owner can optionally grant access permissions to others by writing an access policy. For this operation, a user must get the

s3:PutLifecycleConfiguration

permission.

You can also explicitly deny permissions. Explicit deny also supersedes any other permissions. If you want to block users or accounts from removing or deleting objects from your bucket, you must deny them permissions for the following actions:

• s3:DeleteObject

• s3:DeleteObjectVersion

• s3:PutLifecycleConfiguration

For more information about permissions, see Managing Access Permissions to Your Amazon S3 Resources.

PutObjectAsync(PutObjectRequest, CancellationToken)

Adds an object to a bucket. You must have WRITE permissions on a bucket to add an object to it.

note

Amazon S3 never adds partial objects; if you receive a success response, Amazon S3 added the entire object to the bucket. You cannot use

PutObject

to only update a single piece of metadata for an existing object. You must put the entire object with updated metadata if you want to update some values.

Amazon S3 is a distributed system. If it receives multiple write requests for the same object simultaneously, it overwrites all but the last object written. To prevent objects from being deleted or overwritten, you can use Amazon S3 Object Lock.

To ensure that data is not corrupted traversing the network, use the

Content-MD5

header. When you use this header, Amazon S3 checks the object against the provided MD5 value and, if they do not match, returns an error. Additionally, you can calculate the MD5 while putting an object to Amazon S3 and compare the returned ETag to the calculated MD5 value.

note

• To successfully complete the

  PutObject

  request, you must have the

  s3:PutObject

  in your IAM permissions.

• To successfully change the objects acl of your

  PutObject

  request, you must have the

  s3:PutObjectAcl

  in your IAM permissions.

• To successfully set the tag-set with your

  PutObject

  request, you must have the

  s3:PutObjectTagging

  in your IAM permissions.

• The

  Content-MD5

  header is required for any request to upload an object with a retention period configured using Amazon S3 Object Lock. For more information about Amazon S3 Object Lock, see Amazon S3 Object Lock Overview in the Amazon S3 User Guide.

You have three mutually exclusive options to protect data using server-side encryption in Amazon S3, depending on how you choose to manage the encryption keys. Specifically, the encryption key options are Amazon S3 managed keys (SSE-S3), Amazon Web Services KMS keys (SSE-KMS), and customer-provided keys (SSE-C). Amazon S3 encrypts data with server-side encryption by using Amazon S3 managed keys (SSE-S3) by default. You can optionally tell Amazon S3 to encrypt data at by rest using server-side encryption with other key options. For more information, see Using Server-Side Encryption.

When adding a new object, you can use headers to grant ACL-based permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. By default, all objects are private. Only the owner has full access control. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API.

If the bucket that you're uploading objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don't specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the

bucket-owner-full-control

canned ACL or an equivalent form of this ACL expressed in the XML format. PUT requests that contain other ACLs (for example, custom grants to certain Amazon Web Services accounts) fail and return a

400

error with the error code

AccessControlListNotSupported

. For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide.

note

If your bucket uses the bucket owner enforced setting for Object Ownership, all objects written to the bucket by any account will be owned by the bucket owner.

By default, Amazon S3 uses the STANDARD Storage Class to store newly created objects. The STANDARD storage class provides high durability and high availability. Depending on performance needs, you can specify a different Storage Class. Amazon S3 on Outposts only uses the OUTPOSTS Storage Class. For more information, see Storage Classes in the Amazon S3 User Guide.

If you enable versioning for a bucket, Amazon S3 automatically generates a unique version ID for the object being stored. Amazon S3 returns this ID in the response. When you enable versioning for a bucket, if Amazon S3 receives multiple write requests for the same object simultaneously, it stores all of the objects. For more information about versioning, see Adding Objects to Versioning Enabled Buckets. For information about returning the versioning state of a bucket, see GetBucketVersioning.

WriteGetObjectResponseAsync(WriteGetObjectResponseRequest, CancellationToken)

Passes transformed objects to a

GetObject

operation when using Object Lambda access points. For information about Object Lambda access points, see Transforming objects with Object Lambda access points in the Amazon S3 User Guide.

This operation supports metadata that can be returned by GetObject, in addition to

RequestRoute

,

RequestToken

,

StatusCode

,

ErrorCode

, and

ErrorMessage

. The

GetObject

response metadata is supported so that the

WriteGetObjectResponse

caller, typically an Lambda function, can provide the same metadata when it internally invokes

GetObject

. When

WriteGetObjectResponse

is called by a customer-owned Lambda function, the metadata returned to the end user

GetObject

call might differ from what Amazon S3 would normally return.

You can include any number of metadata headers. When including a metadata header, it should be prefaced with

x-amz-meta

. For example,

x-amz-meta-my-custom-header:
                                                                             MyCustomValue

. The primary use case for this is to forward

GetObject

metadata.

Amazon Web Services provides some prebuilt Lambda functions that you can use with S3 Object Lambda to detect and redact personally identifiable information (PII) and decompress S3 objects. These Lambda functions are available in the Amazon Web Services Serverless Application Repository, and can be selected through the Amazon Web Services Management Console when you create your Object Lambda access point.

Example 1: PII Access Control - This Lambda function uses Amazon Comprehend, a natural language processing (NLP) service using machine learning to find insights and relationships in text. It automatically detects personally identifiable information (PII) such as names, addresses, dates, credit card numbers, and social security numbers from documents in your Amazon S3 bucket.

Example 2: PII Redaction - This Lambda function uses Amazon Comprehend, a natural language processing (NLP) service using machine learning to find insights and relationships in text. It automatically redacts personally identifiable information (PII) such as names, addresses, dates, credit card numbers, and social security numbers from documents in your Amazon S3 bucket.

Example 3: Decompression - The Lambda function S3ObjectLambdaDecompression, is equipped to decompress objects stored in S3 in one of six compressed file formats including bzip2, gzip, snappy, zlib, zstandard and ZIP.

For information on how to view and use these functions, see Using Amazon Web Services built Lambda functions in the Amazon S3 User Guide.
