title: How to prevent Github webhook from triggering when a specific user checks in code
body: <p>The webhook configuration is managed by Jenkins.</p>
  
  <p>I have a job that checks in an updated version file to Github after each successful build.</p>
  
  <p>I'd like to prevent a new build from being triggered when checkin is done from Jenkins.</p>
  
  <p>Is there a way to do this?  Is there a way to prevent the webhook from triggering when a given user performs the checkin?</p>
