    Hello, does anyone know how to use and implement the facebook chat API ?



  • Clint RutkasClint I'm a "developer"

    @Prox and @Joel B, Give me a few to verify this and another thing.

    This article was written long before facebook chat, the updated API may have it.

  • Joel BJoel B

    Prox: I've been wondering the same thing...

  • Clint RutkasClint I'm a "developer"

    @sample application this example is 3 years old, Facebook APIs chances are have shifted.  This is one of the bad things about leveraging other's APIs.  They can change and update and break your application.

    @Documentation head over to facebooktoolkit.codeplex.com they have up-to-date documentation
