I’ve been trying to get X-FACEBOOK-PLATFORM to work for a while.

I keep getting an Unauthorized error every time I try anything.

One of the devs working with me wrote a blog post about it here:
http://www.ianquigley.com/A91_Facebook_Chat_Authentication_in_C.html

That is the basic process that we are using.

The code that we are using is here:

http://code.google.com/p/xda-winmo-facebook/source/browse/#svn%2Ftrunk%2FXDAFacebook%2FFbChat

Basically, I would like some further clarification about the authentication processes and maybe some reasons why I would be getting an unauthenticated message even though I follow the steps on the facebook dev site to a T (at least that is the assumption)

Any help would be great!

Here is the send/receive pattern: (The keys have all been changed FYI)

Key: 123567890560796 Secret: 8f1234abcde123a4567bcd1234beb5e Session: a0b12fb345c67890d98e7ea8.3-12345678

The facebook challenge text
version=1&method=auth.xmpp_login&nonce=B0D022DEA6DDF7AFEB781AF5AC443BA6

and my return challenge text
api_key=123567890560796&call_id=1314990670&method=auth.xmpp_login&nonce=B0D022DEA6DDF7AFEB781AF5AC443BA6&session_key=a0b12fb345c67890d98e7ea8.3-12345678&v=1&sig=e136a4c6a30107f738cf06730c8af6b8

The sig looks like this
api_key=123567890560796call_id=1314990670method=auth.xmpp_loginnonce=B0D022DEA6DDF7AFEB781AF5AC443BA6session_key=a0b12fb345c67890d98e7ea8.3-12345678v=18f1234abcde123a4567bcd1234beb5e

If there are any facebook people that want the real streams with the correct keys, give me a contact address and I’ll send it to you.
