I recently posted a question Facebook Connect - get users friends score on how to get your friends high scores for your app. What I found was the following:
1) /me/friends
with user_friends permissions to get friends with app installed and who have accepted this permission.
2) loop through /{friendID}/scores
to get their high score.
I have not tested this fully as there are only 2 accounts with the app installed so I have the following question:
im using /me/friends?limit=10
as I only want the top ten high scores. Does this automatically bring back the highest or is there another parameter that needs setting to accomplish this?
any information would be appreciated.
edit
Just found that /me/friends?fields=score,picture
will return the all the data in one request. Just need to find out how to get the friends with the highest score
