I have a app scoped user id. Now, I wanted to find its real id but as I went some existing forums like Get Facebook User ID from app-scoped User ID it appears that it is not possible to derive real id from app scoped user id.
But I see that it is possible via https://izitools.com/en/tool/get-facebook-id-from-scoped-id.
Is there any Graph API which can be used to derive real id from the app scoped user id? If it is not possible, we might need to derive app scoped user id from real id.
It seems there is some solution to derive the app scope user id from the real id but could not figure out the solution. Could someone sheds some light on it?
