How to get Mutual Friends via Facebook's Graph API

Question

Is there anyway to get a list of mutual friends using Facebook\'s Graph API?

I\'ve been playing around with this tool and haven\'t yet figured out a way. However, I saw

Answer 1

Goto the API Documentation page here:

http://developers.facebook.com/docs/reference/api/

Mid-way down the page you will see:

•Friends: https://graph.facebook.com/me/friends?access_token=...

You'll need to replace the /me/ with a valid ID of the person you are looking for and you;ll need to get the access_token as well.

Hope this starts you in the right direction..

EDIT: There is also this which may be easier:

Legacy REST method

Answer 2

You can use this one to get mutuals friends from the graph

Answer 3

I would do this as a FQL query and test it with their FQL tester. This might not be 100% what you are looking for, but it should be enough to get you started:

   SELECT uid1, uid2 FROM friend 
   WHERE uid1 IN 
   (SELECT uid2 FROM friend WHERE uid1=me())
   AND uid2 IN 
   (SELECT uid2 FROM friend WHERE uid1=me())

You could then look up these id's up against the user table.
