Looking up FB users by email address?

Jul 26, 2008 at 8:16 PM
Is there a way to do this through the API?  It must be available since Facebook has the capability to look up users from your address book.

I have a db of email contacts & want to be able to see which ones are already on facebook.

Thanks in advance!

That's a bummer.  They seem to have a way to do it manually here: http://www.new.facebook.com/findfriends.php

Yes. manually is different from the API functions.

Midowazzan is correct.  Facebook sadly doesn't expose this in their api
