title: How to set a session id in Postman
body: <p>I need to hit a post request to an API service which requires a session id along with other parameters in its post request field in order to get the required information.</p>
  
  <p>I am using Postman to test this API.</p>
  
  <p>I would like to know how to send a 'session id' in a post request when using Postman?</p>
  
  <p>I am aware of pre-request script in Postman, but I am unaware of how to use the variable in post request.</p>
