Facebook – How to find out if a friend of mine is friend with a mutual friend of mine

facebookfriends

The name of the friend of mine is A and I can see only the mutual friends that we have, not all his friends. The name of the person that I'm not friend with on Facebook but has 3 other mutual friends is B. I can't see his friends either, except his 3 friends we have in common. How to find out if A and B are friends?

Best Answer

You can see the relationship between two users by using their username or Facebook id.

Use the below link if you know the username:

https://www.facebook.com/USER1?and=USER2

Where USER1 is A and USER2 is B.

If you have Facebook id instead of username, use this link:

https://www.facebook.com/profile.php?id=ID1&and=ID2

Where ID1 is A's Facebook id and ID2 is B's Facebook id.

This is the developer way.
