Facebook API - Is it possible to email users when they click "Become a Fan"?

Question

I want to do the following, but not sure if it is possible with the current API. The only thing I found in the AP is the ability to tell if a FB user is a fan. Here goes:

When a user clicks the become a fan button, it sends a custom message (email or facebook email) with url to redeem a code for a free song. The code is obtained from my own custom DB.

Is this possible?

Answer 1

Unfortunately ... no.

You can't define a callback for when someone becomes a friend of a page, so that's out. There's also no way currently to get the list of fans for a page through the API.
