  <p>When I enter a callback url for it, it does call my endpoint correctly, however it's just an HTTP POST and does not contain any body or query parameters or anything I can use to figure out which user deauthorized. I think I'm missing something here.</p>

  <p>But again the HTTP POST still does not give me that <code>signed_request</code>.
  My app is still <code>in development</code> status on the dashboard. This may be the problem but I don't think it is or should be because I should be able to test without releasing.
  Please let me know if you know how to figure out the user who deauthorized your app.
  Thanks!</p>
