title: send POST request in wso2 api manager 4.1.0
body: <p>I want to send a POST request with a body in WSO2. actually, I have a Django rest framework with some APIs and want to send requests in WSO2 API manager. it's all OK for GET, DELETE but when I want to POST some request I'll receive a bad request from Django server.<br />
  Django server is running on http://localhost:8000/user-api/users/<br />
  in wso2 api publisher api's URL is : http://localhost:8243/users/1.0.0<br />
  endpoint in wso2 is : http://localhost:8000/user-api/users/</p>
  <p>the below picture is what I receive when I send GET request:<br />

  and here is what I receive when I send POST request:<br />
  <a href="https://i.stack.imgur.com/FYpFB.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/FYpFB.png" alt="servers response on POST request" /></a></p>
  <p>Everything is ok when I check the server's URL in my browser.</p>
  <p>UPDATE:<br />
  when I use my Django server as a gateway for WSO2 everything is OK but when I use default WSO2-Gateway everything goes wrong.</p>
