Facebook API Common Friends

Question

Is it possible to get common friends using a Facebook API (the intersect of two friends lists)?

For example if you use the Facebook graph API you can do something like

https:..//graph.facebook.com/me/friends

but if you do

https:..//graph.facebook.com/220439/friends

there is a privacy error...

But if you can see the same information with

http://www.facebook.com/friends/?id=220439

So you get the privacy error using the API but the information is publicly available?

So the result is to resort to screen scraping?... Seems odd.

Answer 1

To get access to a user's friends list, you need a valid access token for that user. Then to get the intersection of two friends lists, you would need a valid access token for both users. Retrieve the friends lists separately and then do the intersection in your own code.

As far as I know, it is not possible to get a user's friends list without an access token for that user.
