This document refers to a feature that was removed after Graph API v3.2.
Graph API Version

/{user-id}/invitable_friends

A list of friends that can be invited to install a Facebook game.

The Invitable Friends API is only available to apps classified as Games, which also have a Canvas presence. This API is not available in v1.0. It may be called by mobile games as long as they also have a Canvas presence.

Since Graph API v2.0, /me/friends returns a person's friends who also use the app. You may use the Requests Dialog to invite people to play a game. However, if you want to build a custom multi-friend selector within your game, you need to use call /me/invitable_friends which returns a ranked list of a person's friends who do not play the game, along with a token which can be passed to the Request Dialog in order to invite them. Read our guide on using the Invitable Friends API.
