# DeleteMessage
<a name="API_DeleteMessage"></a>

Deletes the specified message from the specified queue. To select the message to delete, use the `ReceiptHandle` of the message (*not* the `MessageId` which you receive when you send the message). Amazon SQS can delete a message from a queue even if a visibility timeout setting causes the message to be locked by another consumer. Amazon SQS automatically deletes messages left in a queue longer than the retention period configured for the queue. 

**Note**  
Each time you receive a message, meaning when a consumer retrieves a message from the queue, it comes with a unique `ReceiptHandle`. If you receive the same message more than once, you will get a different `ReceiptHandle` each time. When you want to delete a message using the `DeleteMessage` action, you must use the `ReceiptHandle` from the most recent time you received the message. If you use an old `ReceiptHandle`, the request will succeed, but the message might not be deleted.   
For standard queues, it is possible to receive a message even after you delete it. This might happen on rare occasions if one of the servers which stores a copy of the message is unavailable when you send the request to delete the message. The copy remains on the server and might be returned to you during a subsequent receive request. You should ensure that your application is idempotent, so that receiving a message more than once does not cause issues.
