For more information, see Open Web Application Security Project (OWASP): Cross Site Tracing. A request body is data sent by the client to your API. It may seem that we are sending repetitive information via the API, but remember that the request body and path parameters have different meanings and should be used for the purpose that they are going to serve. In the above example, student_id is also part of that resource, so it has to be present in the request body, else the request body would be able to represent the whole resource information. 3.
