Delete message from Azure Storage Queue using REST API

Mike Prager 1

Hi,

I am trying to simply Get a message off an Azure Storage Queue and then delete it using the REST API. I can retrieve the message and get a popreceipt but when I try and use this to delete the message, I keep getting, "The specified message does not exist."

In the documentation (https://learn.microsoft.com/en-us/rest/api/storageservices/delete-message2) it looks like you only have to supply the popreceipt however further down the page, it says,

After a client retrieves a message with the Get Messages operation, the client is expected to process and delete the message. To delete the message, you must have two items of data returned in the response body of the Get Messages operation:

The message ID, an opaque GUID value that identifies the message in the queue.
A valid pop receipt, an opaque value that indicates that the message has been retrieved.

...so this implies you do need to send the MessageId as well but there is nothing in the docs that specifies where to place the actual messageid?

The URI in the docs says to pass DELETE to https://myaccount.queue.core.windows.net/myqueue/messages/messageid?popreceipt=string-value and I have tried replacing messageid with the actual messageid from the GET but this does not seem to be correct.

Has anyone used this and can explain why I always get "The specified message does not exist" when trying to DELETE the message off the queue or am I missing something?

Thanks in advance

Mike

@Mike Prager Firstly can you share the exact command you are using to perform this operation?

Also, can you try adding a timeout value in the Get message request as mentioned here - https://learn.microsoft.com/en-us/rest/api/storageservices/setting-timeouts-for-queue-service-operations

as well as try to increase the visibilitytimeout value in case the request is failing. With respect to the messageID, I do not think you should include this to the Delete request as it only requires the popreceipt value.

Please give it a try and let me know if that helps! Thank you!

Hi,

Thanks for the reply - Apologies for not replying sooner.
I am setting the VisibilityTimeout to quite high as this was my first thought although the delete is happening almost instantaneously after I get the message.

Here is what I use to retrieve the message

GET https://myacct.queue.core.windows.net/myqueuename/messages?visibilitytimeout=120

This seems to work fine.

Then I try to delete the message

DELETE https://myacct.queue.core.windows.net/myqueuename/messages/messageid?popreceipt=%PopReceipt%

where %PopReceipt% is the popreceipt I get from the GET.

I get the error I mentioned before.

If I use the Azure Storage library off Nuget, it works fine however what is strange is that to delete a message, you need both the MessageId AND the PopReceipt whereas in the REST call, it only looks like from the Docs you can pass the PopReceipt but as I said, lower down the Docs it says you do need the MesssageId as well.

Thanks

Mike

@Mike Prager I apologize for the time taken while I was reproducing this issue.

I see that if you use only the popreceipt parameter in the Delete API, it will delete the message. If you try to use the messageID, it throws errors that the message does not exist. However, as you mentioned, the doc mentions the need for the MessageID, I will reach out to the internal team regarding this and will update yon soon. In the meanwhile, please let us know if you have any further questions and we will be glad to assist you further. Thank you!

Can you share the code you tested this out with so I can try it on my queue as I can't get it to work just using a PopReceipt only?

Thanks

Mike

https://myaccount.queue.core.windows.net/myqueue/messages<sastoken>&popreceipt=string-value

Example- https://myaccount.queue.core.windows.net/test569/messages?sv=2021-06-08&sa=abcd&srt=azu&re=rwdlacupiytfx&se=2022-08-09T07:58:25Z&st=2022-08-08T23:58:25Z&spr=https&sig=%2A2BzIHaHBjHmjbpRYdBO1gIQ2UGXrdLGz%2B0fFNKoYdo%3D&popreceipt=BBBBMBBBBBBBBJ6EoQIKr2AE=

I used postman to GET API the message, noted the popreceipt number and then used DELETE API to delete the message with the respective popreceipt and it was deleted.

@Mike Prager Have you tried using the above syntax and did that work for you? Please let me know. Thanks!

Hi, I'm also struggling with this issue at the moment and I note that in your example above you use the /messages endpoint rather than messageId. This is the delete endpoint noted in the clear messages call, not to pop a single message.

https://learn.microsoft.com/en-us/rest/api/storageservices/clear-messages

It does work and does delete all messages from the queue but I cannot get it to work one at a time using messageId and the a messages' PopReceipt.

I am facing the same issue.

DELETE https://myacct.queue.core.windows.net/myqueuename/messages/<messageid>?popreceipt=<PopReceipt>

I am passing the messageid and PopReceipt Id from the Get results but getting the below error:

<?xml version="1.0" encoding="utf-8"?> <Error> <Code>AuthenticationFailed</Code> <Message>Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.
