Return Email from friends Facebook friend_list

Question

Using the Graph-API from Facebook I can get various data from the user who is logged in to my system (a full list can be seen on Facebook doc). However, I would like to know if there is a way to get the data from my friends, to be more specific, the email.

I know I can use the taggable_friends to mark friends who don’t use my app, and invitable_friends to be able to invite friends (if you use canvas). However, in none of these ways can I recover the email from the friend?

Large companies, such as the Yahoo can perform this email import. This can be done through the facebook API?

Answer 1

Unfortunately the Facebook restricted some functionality in order to keep the privacy of users. With this, it is not possible to get the email in the desired way.

Large companies have a "gentlemen’s agreement" to obtain this data, which is normal in any large API in the market.
