Parameters

string $audience

The audience for the credential.
string $regionalCredVerificationUrl

The regional AWS GetCallerIdentity action URL used to determine the AWS account ID and its roles. This is not called by this library, but is sent in the subject token to be called by the STS token server.
string $regionUrl

This URL should be used to determine the current AWS region needed for the signed request construction.
string $securityCredentialsUrl

The AWS metadata server URL used to retrieve the access key, secret key and security token needed to sign the GetCallerIdentity request.
string $imdsv2SessionTokenUrl

Presence of this URL enforces the auth libraries to fetch a Session Token from AWS. This field is required for EC2 instances using IMDSv2.
