Facebook unity sdk: is it possible to send friend invites/app requests to non app users?

Question

I'm working with the official facebook sdk and example scene for unity and am sending app requests using : FB.AppRequest() which returns a list of friends to send invites to.

However no matter what I try, I only get a list of friends associated with the app and cannot see any other friends who haven't played the app.

I have even tried setting the 'app_non_user' filter, but this makes no difference.

I have read on the Invitable_Friends api, but am not sure how this would be implemented in the unity sdk.

Any advice would be much appreciated. Thanks

Your app must be approved by Facebook to get people's friends lists beyond people using the app. Look in the developers.facebook.com section to find how to do this. I haven't done this, but a game I worked on needed to do this.

Getting approved involves sending your app and it goes through an approval process.

Here's the relevant bit:

"If your app is a game and has a presence on Facebook Canvas:

You can use the requests Dialog and set filters=app_non_users to filter the dialog to only show people who don't use the app."
