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".
sns_confirm_subscription(TopicArn, Token, AuthenticateOnUnsubscribe)[required] The ARN of the topic for which you wish to confirm a subscription.
[required] Short-lived token sent to an endpoint during the Subscribe action.
Disallows unauthenticated unsubscribes of the subscription. If the value
of this parameter is true and the request has an AWS signature, then
only the topic owner and the subscription owner can unsubscribe the
endpoint. The unsubscribe action requires AWS authentication.
