What kinds of Social Data and Interactions Can you Request
Why do you authenticate ---
- to get user or friend social data from Facebook to your app (only for user currently using the application).
- to perform "social" interactions on behalf of user using your app in Facebook like messaging, inviting, newsfeeds, wall posts and more.
Examples of Social Data
NOTE FROM FACEBOOK: A full list of permissions is available in our permissions reference. There is a strong inverse correlation between the number of permissions your app requests and the number of users that will allow those permissions. The greater the number of permissions you ask for, the lower the number of users that will grant them; so we recommend that you only request the permissions you absolutely need for your app.
