How to Peek-Lock Message and not Receive and Delete on Azure Service Bus Topic using REST Client

Question

At Microsfot Docs I don't saw the diference from Receive and Delete Message from Peek-Lock Message. The Request is the same.

I tried the request using Postman. How to use Peek and how to use Delete? See the documentation link:

https://docs.microsoft.com/en-us/rest/api/servicebus/peek-lock-message-non-destructive-read

https://docs.microsoft.com/en-us/rest/api/servicebus/receive-and-delete-message-destructive-read

If you closely look at the HTTP Request methods, for Peek Lock the request method is Post while for Receive and Delete it is Delete .

If you want to Peek Lock a message, you will need to use HTTP POST method.

However, please keep in mind that Peek Lock method dequeues a message from the queue and it will remain invisible to other callers for certain duration. Furthermore after a message has been dequeued a certain number of times, it will be dead lettered.

Unfortunately simple peeking at a message (ie fetching a message without dequeuing it) is not possible with REST API (HTTP Protocol). You will need to use AMQP protocol to do so.
