Is there a way to get the ID of a message thread in Facebook? [closed]

Question

If I have the URL of a facebook thread from a user's messages, is there a way to get the id of that thread? I get how to construct a url given an id, but not the other way around.

The URL can have two formats:

https://www.facebook.com/messages/123456789 or https://www.facebook.com/messages/<username>

I need to be able to handle both cases.

Thanks.

SELECT thread_fbid 
  FROM unified_thread 
 WHERE single_recipient = <USER ID>

Doc: https://developers.facebook.com/docs/reference/fql/unified_thread

This gives exactly what you want. The problem is:

(#298) You must be a developer of the application

Please read unified_thread still not open for public?

So, one actual workaround would be to loop on all the threads from graph.facebook.com/me/inbox?fields=to as long as you didn't find one which:

• has only 2 participants (because some threads are group conversations and you don't want them),
• and contains the participant who is the person represented by a user ID/username.

This has to be done manually, using your favorite language.
