title: All Facebook messages from Graph API
body: <p>I'm building an application for my personal use that saves all my facebook messages in a database on my computer.</p>
  
  <p>But I have a problem as it seems only few messages can be accessed through the Graph API.
  I created a token with all the possible permissions.</p>
  
  <p>When issuing a call:</p>
  
  <pre><code>/me/inbox
  </code></pre>
  
  <p>I get all the threads in my inbox but for some of them the <code>comments</code> field which contains the actual messages is missing. It's mostly for conversation with people that are not friend with me on facebook.</p>
  
  <p>For those threads, when I try to get more information by <code>/&lt;id_of_the_thread&gt;</code>
  I get an error (code 100) <code>Unsupported get request.</code> from the graph api.</p>
  
  <p>Is it a normal behaviour of the API?
  What am I missing here?</p>
  
  <p>Don't hesitate if you know a better way of saving all my messages.</p>
