Is there any way to exclude non app users from taggable friends
I know with latest version of facebook , it has 2 separate api to retrieve app users through /friends and non app users through /taggable, but taggable friends api is also returning app users
is there any way to separate them?
With v2.0+ not really. You could use me/invitable_friends but that permission has to be reviewed and it is only allowed for Games on the Facebook Canvas to invite friends to an app and for no other purpose.
