title: JMeter: Failed using POST method with filters in URL and JSON in body
body: <p>Firstly I searched the forum but couldn't find something relevant (hope I hadn't skipped anything, I'm really a beginner).</p>
  
  <p>What I'm trying to do is validate a POST request (no cookies, no login credentials, only API access key)</p>
  
  <p>Example URL for POST in Postman:</p>
  
  <pre><code>https://devenv.myapp.mainhomepage.com/api/v4/gpp-category?access_key=xyzxyz000111222333444&amp;filter[to]=app001&amp;filter[from]=comp9&amp;filter[service]=mobile
  </code></pre>
  
  <p>(I wrote the access_key in URL, but in Postman works both in URL and in Headers as key: Authorization, value: xyz01234..)</p>
  
  <p>Example BODY for POST in Postman:</p>
  
  <pre><code>{ 
     "data":{ 
        "type":"gpp-category",
        "attributes":{ 
           "standard":{ 
              "appid": "app001",
              "name": "Java",
              "developer": "Oracle",
              "discontinued": false,
              "scraper_1": "test-1"
           },
           "relationships":{ 
              "to":{ 
                 "data":{ "type":"gpp-category", "id":"app001" }
              },
              "from":{ 
                 "data":{ "type":"gpp-category", "id":"comp9" }
              }
           }
        }
     }
  }
  </code></pre>
  
  <p>Now, here's what I'm doing in JMeter:</p>
  
  <pre><code>1. Thread Group with HTTP Header Manager (Content-Type - application/json)
  2. HTTP Request where: 
  Server Name: devenv.myapp.mainhomepage.com
  Path: /api/v4/gpp-category?access_key=xyzxyz000111222333444&amp;filter[to]=app001&amp;filter[from]=comp9&amp;filter[service]=mobile
  Body Data: the above example of body.
  </code></pre>
  
  <p>The response data in View Results Tree is:</p>
  
  <pre><code>{"data":[]}
  </code></pre>
  
  <p>Question: Is it from parameters or the response I received isn't decoded? Post wasn't successful, I tried GET for that id and it couldn't be found.</p>
