title: How do I pass the commit SHA as a parameter in GITLab WebHook
body: <p>I want to trigger a Jenkins Job if there is code commit made to Gitlab</p>
  
  <p>I am using WebHooks for this:
  <a href="https://i.stack.imgur.com/bAhwF.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bAhwF.png" alt="enter image description here"></a></p>
  
  <p>The URL I am trying is</p>
  
  <pre><code>http://10.192.39.32:1024/job/SCMSnaps/buildWithParameters?token=secretkey&amp;SNAP=$GIT_COMMIT
  </code></pre>
  
  <p>I want SNAP to hold the value of the SHA Number on the Gitlab </p>
  
  <p>can anyone help with the correct way to pass variables in a WebHook URL?</p>
