title: How to add a comment to a work item using Visual Studio Team Services REST API
body: <p>Is it possible to add a comment to a work item in Visual Studio Team Services using the REST API?</p>
  
  <p>I've checked the <a href="http://www.visualstudio.com/integrate/reference/reference-vso-work-item-overview-vsi" rel="nofollow noreferrer">work item doc</a> and <a href="http://www.visualstudio.com/integrate/reference/reference-vso-work-item-fields-vsi" rel="nofollow noreferrer">fields doc</a> but I couldn't see anything in the fields JSON which looked like it's the comments field.</p>
  
  <p>The scenario I'm trying to achieve is CCing an email to <a href="https://zapier.com/" rel="nofollow noreferrer">Zapier</a> and having the body of the email added as a comment on the work item in VSO. </p>
