It seems that I can not find the answer to a very simple question, I am sure that I am missing something obvious.
My application works fine (it has been for several months), it is a fairly simple application that strictly uses the javascript API (inside iFrame). I currently need to implement tracking, which detects when new users first add an application, but I cannot figure out how to do this.
Docs don't help: http://developers.facebook.com/docs/authentication/
Authentication works fine, but there seems to be no information sent back that says, “Hey, this is this first user visit” or “hey, this is a return visitor.” What am I missing here? How can I track this? Is there a parameter?
Any advice would be greatly appreciated!
