Is there any way to check whether an authenticated user is friend with another given user, not necessarily using the app? For example, knowing if the currently logged user is friend with mark?
It used to be possible querying "/me/friends/[user_id]", but the "/me/friends" endpoint only returns friends who use the app from 2.0 onwards (see https://developers.facebook.com/docs/graph-api/reference/v2.2/user/friends).
Any alternative?
