Decodes additional information about the authorization status of a request from an encoded message returned in response to an AWS request.

For example, if a user is not authorized to perform an action that he or she has requested, the request returns a

CopyC#
Client.UnauthorizedOperation
response (an HTTP 403 response). Some AWS actions additionally return an encoded message that can provide details about this authorization failure.

Note:
Only certain AWS actions return an encoded authorization message. The documentation for an individual action indicates whether that action returns an encoded message in addition to returning an HTTP code.

The message is encoded because the details of the authorization status can constitute privileged information that the user who requested the action should not see. To decode an authorization status message, a user must be granted permissions via an IAM policy to request the

CopyC#
DecodeAuthorizationMessage
(
CopyC#
sts:DecodeAuthorizationMessage
) action.

The decoded message includes the following type of information:
