title: Handling Callback URLs in JMeter
body: <p>My REST Service takes in a JMeter HTTP request and one of the parameters in the request is a callback url.</p>
  
  <p>The REST Service uses this callback url to post back a response.</p>
  
  <p>Is there any JMeter Listener I can use to receive the callback i.e. so that the REST Service can send the response back to a JMeter Listener.</p>
  
  <p>And if possible the Listener can then send in another HTTP Request based on the response.</p>
