Question

Naturally the documentation doesn’t make this distinction, which makes me think it doesn’t. So very succinctly – does anyone know whether a user losing a friend triggers a realtime update callback? If so, is it the same if the user removed said friend or if the user was ‘unfriended’?

If I’ve missed something in the documentation about this then I apologise, but I assure you I have looked.

The Facebook Realtime API does seem to be providing notifications about certain user fields and connections for the User object. Connections to which you can subscribe include for User object include: feed, friends, likes, checkins, location, events.

And when you have successfully subscribe for user object subscription, everytime users friends is updated, your callback server will be notified.
