Unsubscribe - 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).

Unsubscribe

Deletes a subscription. If the subscription requires authentication for deletion, only the owner of the subscription or the topic's owner can unsubscribe, and an Amazon signature is required. If the Unsubscribe call does not require authentication and the requester is not the subscription owner, a final cancellation message is delivered to the endpoint, so that the endpoint owner can easily resubscribe to the topic if the Unsubscribe request was unintended.

Note

Amazon SQS queue subscriptions require authentication for deletion. Only the owner of the subscription, or the owner of the topic can unsubscribe using the required Amazon signature.

This action is throttled at 100 transactions per second (TPS).
