I've been trying to setup auth provider login with facebook. I've followed the instructions online, have generated an authentication handler and customised.
However when I try logging in (through community) the facebook Auth.UserData passed into createUser method does not contain a username, email, first name or last name. It does however have the full name.
Is there something in the config (either Salesforce side or within my Facebook app) that I am missing?
Any help would be greatly appreciated!
