HttpTokens

The state of token usage for your instance metadata requests.

string? HttpTokens { get; }

Property Value

string

Remarks

If the parameter is not specified in the request, the default state is optional .

If the state is optional , you can choose to retrieve instance metadata with or without a signed token header on your request. If you retrieve the IAM role credentials without a token, the version 1.0 role credentials are returned. If you retrieve the IAM role credentials using a valid signed token, the version 2.0 role credentials are returned.

If the state is required , you must send a signed token header with any instance metadata retrieval requests. In this state, retrieving the IAM role credentials always returns the version 2.0 credentials; the version 1.0 credentials are not available.
