title: How to convert JSON GET request to HTTP PATCH request
body: <p>I want to convert a HTTP GET request to a HTTP PATCH request. I am accessing TFS APIs and I want to lock my build automatically by using a patch request.</p>
  
  <p>Currently I am getting all the information by GET method. Now I want to update <code>keepForever</code> from false to true using the HTTP PATCH method. By GET method I am able to do that but now I have to do that by HTTP Patch method.</p>
  
  <p>Can someone help me converting the below code from GET method to POST method?</p>
