Getting friends of friends in FB graph API

Question

I would like to get friends of friends via an API call and when I try to do it, I get the following exception,

    {
   "error": {
      "type": "OAuthException",
      "message": "(#604) Can't lookup all friends of .... Can only lookup for the logged in user (...), or friends of the logged in user with the appropriate permission"
   }
}

The URL I am trying to access is,

https://graph.facebook.com/friend_id/friends?access_token=access_token

I am getting extended permissions which is as follows,

<fb:login-button perms="user_likes,friends_likes"></fb:login-button>

Could any one please let me know what's going wrong here? Or does it mean I can never get access to friends of friends?

Answer 1

Currently, there is no extended permission that allows you to view a user's friends of friends. The "*_likes" permissions just show you the Facebook pages that the users have Liked.

It might be possible for you to iteratively fetch and cache the friends of each of the user's friends, one by one, but without access tokens for each friend, you'll only be able to fetch public data.

Answer 2

I got friends of friends(limited). I had same problem. Though it is very late for answering question, it will help somebody. That's why answering this question.

We can get friends of friends those are app users. $fb_id= user id whose friends of friends required.

$query="SELECT uid, name, work_history FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1 IN (SELECT uid FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1 = $fb_id ) and is_app_user=1) )"; $user_info=$facebook->api(array('method'=>'fql.query', 'query'=>$query));

@Olie:

You are fetching your friends of your friend through application. So you would need permission from your friend whose friends you want. i.e. Your friend should be using that application and accepted those permission while allowing accessing information. Otherwise you wont be able to friends of your friend. I have tested this query. And it works successfully.

"message": "(#604) Can't lookup all friends of .... Can only lookup for the logged in user (...), or friends of the logged in user with the appropriate permission"

This message explains well. Read carefully.

Hope you understand solution criteria.
