title: In Jmeter, What would be syntax of parameters in Body Data section of HTTP Request Sampler, if I am using Rest APIs and taking input from CSV files?
body: <p>I am trying to create 10 users at the same time in Jmeter, using REST APIs.</p>
  <p>Test Data i.e. input is taken from CSV files (The details of users like user name, last name , mobile)</p>
  <p>For this I have added one thread group,User Defined Variable,HTTP Header Manager, HTTP Request Sampler (which perform successful login into web application), JSON PATH EXTRACTOR ( to extract auth token, which will be used while adding user)</p>
  <p>To Add User, I have used one &quot;Loop Controller&quot; - &quot;HTTP Request Sampler&quot; - HTTP Header Manager, CSV Data Set Config.</p>
  <p>And to track result, View Results Tree and Aggregate Report.</p>
  <p>Please tell me what would be the syntax of parameters which I am passing in &quot;Body Data&quot; section of HTTP Request sampler, so that it can read values from csv files.</p>
  <p>Below is the syntax I am using now to add single user.</p>
  <pre><code>{
    &quot;phoneNo&quot;: &quot;9998885551&quot;,
    &quot;lastName&quot;: &quot;john25&quot;,
    &quot;email&quot;: &quot;azp25@gmail.com&quot;,
    &quot;firstName&quot;: &quot;ricky25&quot;,
    &quot;mobileNo&quot;: &quot;9820420420&quot;
  }
  </code></pre>
