ConfirmSubscription - Amazon Simple Notification Service
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).


Verifies an endpoint owner's intent to receive messages by validating the token sent to the endpoint by an earlier Subscribe action. If the token is valid, the action creates a new subscription and returns its Amazon Resource Name (ARN). This call requires an AWS signature only when the AuthenticateOnUnsubscribe flag is set to "true".
