title: Facebook - Get conversation thread ID with message ID?
body: <p>When I receive a "message received callback" event from the Facebook Realtime API (webhooks) I want to fetch previous messages in the conversation. To do that I need the ID of the conversation thread.</p>

  <p>The event does not contain any information about the ID of the conversation thread (t_id). It only contains the message ID (mid).</p>

  <p>Is there a way to get the conversation thread ID?</p>
