Examples

             // The values are placeholders you should change.
             using Amazon.CDK.AWS.APIGateway;

             var cfnAuthorizerProps = new CfnAuthorizerProps {

                 RestApiId = "restApiId",
                 Type = "type",

                 // the properties below are optional
                 AuthorizerCredentials = "authorizerCredentials",

Remarks

Properties

AuthType

Optional customer-defined field, used in OpenAPI imports and exports without functional impact.

string? AuthType { get; }

Property Value

string

Remarks

AuthorizerCredentials

Specifies the required credentials as an IAM role for API Gateway to invoke the authorizer.

string? AuthorizerCredentials { get; }

Property Value

string

Remarks

To specify an IAM role for API Gateway to assume, use the role's Amazon Resource Name (ARN). To use resource-based permissions on the Lambda function, specify null.

AuthorizerResultTtlInSeconds

The TTL in seconds of cached authorizer results.

double? AuthorizerResultTtlInSeconds { get; }

Property Value

double?

Remarks

If it equals 0, authorization caching is disabled. If it is greater than 0, API Gateway will cache authorizer responses. If this field is not set, the default value is 300. The maximum value is 3600, or 1 hour.

Link: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-apigateway-authorizer.html#cfn-apigateway-authorizer-authorizerresultttlinseconds

AuthorizerUri

Specifies the authorizer's Uniform Resource Identifier (URI).

string? AuthorizerUri { get; }

Property Value

string

Remarks

For TOKEN or REQUEST authorizers, this must be a well-formed Lambda function URI, for example, arn:aws:apigateway:us-west-2:lambda:path/2015-03-31/functions/arn:aws:lambda:us-west-2:{account_id}:function:{lambda_function_name}/invocations . In general, the URI has this form arn:aws:apigateway:{region}:lambda:path/{service_api} , where {region} is the same as the region hosting the Lambda function, path indicates that the remaining substring in the URI should be treated as the path to the resource, including the initial / . For Lambda functions, this is usually of the form /2015-03-31/functions/[FunctionARN]/invocations .

IdentitySource

The identity source for which authorization is requested.

string? IdentitySource { get; }

Property Value

string

Remarks

For a TOKEN or COGNITO_USER_POOLS authorizer, this is required and specifies the request header mapping expression for the custom header holding the authorization token submitted by the client. For example, if the token header name is Auth , the header mapping expression is method.request.header.Auth . For the REQUEST authorizer, this is required when authorization caching is enabled. The value is a comma-separated string of one or more mapping expressions of the specified request parameters. For example, if an Auth header, a Name query string parameter are defined as identity sources, this value is method.request.header.Auth, method.request.querystring.Name . These parameters will be used to derive the authorization caching key and to perform runtime validation of the REQUEST authorizer by verifying all of the identity-related request parameters are present, not null and non-empty. Only when this is true does the authorizer invoke the authorizer Lambda function, otherwise, it returns a 401 Unauthorized response without calling the Lambda function. The valid value is a string of comma-separated mapping expressions of the specified request parameters. When the authorization caching is not enabled, this property is optional.

IdentityValidationExpression

A validation expression for the incoming identity token.

string? IdentityValidationExpression { get; }

Property Value

string

Remarks

For TOKEN authorizers, this value is a regular expression. For COGNITO_USER_POOLS authorizers, API Gateway will match the aud field of the incoming token from the client against the specified regular expression. It will invoke the authorizer's Lambda function when there is a match. Otherwise, it will return a 401 Unauthorized response without calling the Lambda function. The validation expression does not apply to the REQUEST authorizer.

Name

The name of the authorizer.

string Name { get; }

Property Value

string

Remarks

ProviderArns

A list of the Amazon Cognito user pool ARNs for the COGNITO_USER_POOLS authorizer.

string[]? ProviderArns { get; }

Property Value

string[]

Remarks

Each element is of this format: arn:aws:cognito-idp:{region}:{account_id}:userpool/{user_pool_id} . For a TOKEN or REQUEST authorizer, this is not defined.

Link: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-apigateway-authorizer.html#cfn-apigateway-authorizer-providerarns

RestApiId

The string identifier of the associated RestApi.

string RestApiId { get; }

Property Value

string

Remarks

Type

The authorizer type.

string Type { get; }

Property Value

string

Remarks

Valid values are TOKEN for a Lambda function using a single authorization token submitted in a custom header, REQUEST for a Lambda function using incoming request parameters, and COGNITO_USER_POOLS for using an Amazon Cognito user pool.
