Request verbs are also known as request methods, which are used by a web application client to indicate the desired action to be performed for a given resource on the server. Each of the methods used depends upon the resources required by the client from the server. Some of the most common HTTP verbs are GET, POST, OPTIONS, HEAD, PUT, DELETE, TRACE, PATCH, and CONNECT.

Fuzzing HTTP request methods can help us to identify the changes in a web application's responses based on different methods being supplied by the fuzzer. We can also identify the methods allowed by the web application server, which can be used to check a few attack test cases.
