Social Authentication User profile

Hi There, 

I have a need to use FortiAuthenticator Social Login and keep the user login information for further marketing purposes.  On a lab, I was able to use several social networks to authenticate myself, but the only information that I have logged on FortiAuthenticator is the first and last name ... 

I can see that during the social authentication process, facebook for example sends the User information back to authenticator, as name, e-mail, and complete profile info .. 

Does anyone have more information about how does that work ? 

I appreciate any help.
