I was searching for any way to get the mutual friends on facebook and i got this one
https://developers.facebook.com/tools/explorer/?method=GET&path=me%2Fmutualfriends%2F&version=v2.0
But i found out that it is deprecated !! although Tinder got shared friends on Facebook.
So is there any way that i can get mutual friends on facebook on my iOS app?
Since API v2.0, you (after granting user_friends permission) can only get the list of mutual friends with a user that also granted user_friends permission. The list will only have mutual friends that are using your app and granted user_friends permissions.
Please, see https://developers.facebook.com/docs/graph-api/reference/v2.0/user.context/mutual_friends
Cheers!
Update: The All Mutual Friends API feature was deprecated for Graph API v3.1 on July 26, 2018, and will be deprecated for all versions on October 24, 2018.
