title: JavaScript - Trigger Twitter intent "follow" callback only if user actually follows
body: <p><strong>Product I am working on:</strong> Requestly - Chrome and Firefox Extension Setup redirects, modify headers, switch hosts, insert user scripts (<a href="https://www.requestly.in/" rel="nofollow noreferrer">https://www.requestly.in/</a>)</p>
  
  <p><strong>What I am trying to do:</strong> Requestly offers free 30 days access to GOLD Plan if user completes a set of few steps. One of such steps is to follow us on Twitter. I want to verify if the user has actually followed us on Twitter.</p>
  
  <pre><code> //After loading widgets.js    
      function followIntent (intentEvent) { 
          console.log("User Followed")
      };    
      twttr.ready(function (twttr) {
        twttr.events.bind('follow', followIntent);
      });
  </code></pre>
  
  <p><strong>Problem:</strong> The "followIntent" function is getting triggered as soon as user clicks the Follow button. I want it to be called only after user has successfully followed us. How can I achieve this?</p>
