In my App, I go through different groups and pages, and check public posts that were posted by people that haven't installed my App. How can I tell if a person that posted something is a friend of mine or not?
I am well aware that \me\friends returns only the list of friends who also installed my app, I don't want to get the full list, only check a specific person. I am also well aware that Facebook currently returns app-scoped Facebook ID of a user of enters my application, but also returns public data about people using their non-app-scoped FB ID - however without this simple piece of info.
Thanks in advance
Unfortunately this is not possible until both persons have given your app the user_friends permission.
