Adobe just released the “ActionScript 3.0 Client Library for Facebook Platform API”, which is a wordy name for a pretty straightforward AS3 Facebook API we’ve been working on for the past few weeks.
The library is an updated version of a library originally developed by Jason Crist. We’ve been working with Adobe, Facebook, and Jason to extend it to support all of the Facebook APIs (Canvas, Connect, and Desktop), and to clean up some of the code. That’s not to imply that Jason’s original work wasn’t great, there’s just a limit to how much you can do for free as one guy on an open source project.
The end result is an open source AS3 API that mirrors the documented Facebook API almost exactly. We’ve also added a few helper methods, and some samples to make it easier to get started.
