So I've been trying for this for a couple of days, trying to figure out how to use Facebook's Graph API v2.2 to get mutual friends between two users. I understand that I can only get the mutual friends between two users that are using the FB App and that's cool.
The app has the following approved items:
- public_profile
- user_birthday
- user_friends
- user_hometown
- user_location
- user_relationships
- user_website
My scenario is this:
- A user (user A) register to the FB App
- Another user (user B) registers
- User A looks at the user B's profile
- The profile should display the mutual friends between the two users
I've tried to play around in the Graph API Explorer
/v2.2/app_scoped_user_id?fields=context.fields%28mutual_friends%29
and
/v2.2/user_id?fields=context.fields%28mutual_friends%29.
These just returns an ID field with the ID I provided and nothing else.
I'm all out ideas, and the docs isn't helping much either. Can someone explain how to do it? I will be using it in an Angular app but as long as I can get the URL to fetch the correct thing I can translate it into Javascript.
For v2.3 - https://developers.facebook.com/docs/graph-api/reference/v2.3/user.context/mutual_friends
Between friends make sure the user_id in the query is the Facebook id of the other friend not the current user whose access token you are using.
GET /v2.3/{other_user.user-id}?fields=context.fields%28mutual_friends%29For querying mutual friends between two non-friends you need to add a server appsecret_proof parameter plus the user access token.
