Using facebook sdk to show ALL mutual friends, not just those with the app?

I am using javascript sdk on facebook and I want to show ALL the mutual friends between these users, not just the ones with the app.

Using the api documentation here , I can only see the list of facebook friends who have the app.

How can I get a complete list of friends?

The additional notes on this page explain it pretty well why you can't get everything.

  • A valid user access token with user_friends permission is required to view other friends' mutual friends using the app.
  • The user in the request and the session user must grant the user user access rights.
  • Also, the answer will only include mutual friends that have given users user_friends.


That is, the only way to get a complete list of mutual friends is if all your friends have joined your app and have granted user_friends permissions

What is the end point for all friends:

https://developers.facebook.com/docs/graph-api/reference/v2.5/user-context/all_mutual_friends



Returns a list of all Facebook friends that have session user and request user. This includes friends who are using the app as well as friends who are not using the app.

It also says that you must request this endpoint from your server, not the application client.
