The Facebook API can do this for you. They also have a demo that has the code to do that.
Github Code for FriendSmash in unity
You’ll want to check out Assets/Scripts/GameStateManager.cs around line: 126
That should pretty much cover it, look over the Facebook example, there are plenty of tidbits in there to get you going using their API to do whatever it is you kids do with Facebook.
