title: How to send a lot of POST request in JSON format through JMeter?
body: <p>So I have this huge file of json requests that I need to send to an API through POST, they are about 4000 different requests. I tried the CSV method and reference the JSON_FILE in code but it didn't work due to a timeout error, I think 4000 files is just too much for this method</p>
  <p>I <em>could</em> create 4000 thread groups, each one with it's individual json request but that would be a huge manual labor</p>
  <p>Is there anyway to automatize this process?</p>
  <p>The json looks basically like this</p>
  <pre><code>{
      &quot;u_id&quot;: &quot;00&quot;,
      &quot;u_operation&quot;: &quot;Address&quot;,
      &quot;u_service&quot;: &quot;Fiber&quot;,
      &quot;u_characteristic&quot;: 2,
      &quot;u_name&quot;: &quot;Address #1&quot;
  },
  {
      &quot;u_id&quot;: &quot;01&quot;,
      &quot;u_operation&quot;: &quot;Address&quot;,
      &quot;u_service&quot;: &quot;TV&quot;,
      &quot;u_characteristic&quot;: 2,
      &quot;u_name&quot;: &quot;Address #2&quot;
  }
  </code></pre>
  <p>All the way up to 4000</p>
