-- 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".
