Check if multiple user ids are friends with a particular person

Question

I want to know which people in a list of people are friends with this user. Is there a graph api call that can return the subset of ids that is the user's friends? I've tried:

/me/friends/?ids=xxxxx,xxxx

I know I can use a batch call an do something like this:

/me/friends/xxxx /me/friends/xxxxx

but it would be nice to do it in one call.

Answer 1

There wasn't an easy way to do this with the graph api, but I was able to do it with an FQL query:

query = '{
"are_friends":"SELECT+uid2+FROM+friend+WHERE+uid1=me()+and+uid2+in('+people_array.join()+')+limit+10",
"friend_meta":"SELECT+uid,first_name,last_name,name,pic_square+FROM+user+where+uid+in(SELECT+uid2+FROM+%23are_friends)"}'

The friend_meta json object in the result will have all the meta info you are looking for. It's one call, and more efficient and cleaner than the batch calls.
