I have an application that uses the old REST API call Friends.getAppUsers
to get the list of friends for the current user that have authorized my application.
I have read the documentation, how do I do this with the Graph API? What would an example of this be?
I searched around for a while, and I too thought this wasn't possible using Graph API.
However, I posted a similar question, Replacement for old GetAppUsers call to see a user's friends who use my application?, for the specific API I was using and was given a great general answer.
https://graph.facebook.com/me/friends?fields=installed
or more generally
https://graph.facebook.com/{user id}/friends?fields=installed
This returns all friends, with the additional field "installed=true" for those friends who use the application.
Here is it working in the Graph API Explorer:
