body: <p>I am using post request With JSON Object:</p>
  
  <pre><code>{
       "name": "Emmy",
       "age": 11,
       "state": "Goa",
       "country": "india"
  }
  </code></pre>
  
  <p>my CSV file is :</p>
  
  <pre><code>name,age,state,country
  Emmy,11,Goa,india
  </code></pre>
  
  <p>and my artilery code :</p>
  
  <pre><code>config:
    target: 'http://localhost:5000'
    phases:
      - duration: 60
        arrivalRate: 10
    defaults:
      headers:
        token: 'TOKEN'
    payload:
      path: "./hello.csv"
      fields:
        - "name"
        - "age"
        - "state"
        - "country"
  scenarios:
    - flow:    
      - post:
          url: "url"
          json:
           name: "{{name}}" 
           age: "{{age}}"
           state: "{{state}}"
           country: "{{country}}"
