Get Facebook app-scoped user id from global Facebook id, or username

Question

If you have a Facebook, for instance Zuckerbergs user id '4', or username, 'zuck', how do you get the new app-scoped id with Graph v2.0 using the app's access token? Can't seem to find anything about this in the docs.

If you are trying to determine whether an id is app scoped, user ids fall in the range [(id < 2200000000 || (id >= 100000000000000 && id <= 100099999989999)](https://github.com/facebookarchive/facebook-js-sdk/blob/deprecated/src/xfbml/helper.js#L37). App scoped user ids will fall outside of this range — Matthew Kolb, Sep 28 '20 at 21:10

This is basically the answer given to the other-way-around question, Get Facebook User ID from app-scoped User ID .

Basically, easiest straight forward flow is a call to https://graph.facebook.com/?ids=http://facebook.com/[FBID/USERNAME]&access_token=[APP_ID]|[APP_SECRET]

Doing that for Zuckerberg, will give you the familiar

{
  "http://facebook.com/4":
  {
    "id": "4",
    "first_name": "Mark",
    "gender": "male",
    "last_name": "Zuckerberg",
    "link": "https://www.facebook.com/zuck",
    "locale": "en_US",
    "name": "Mark Zuckerberg",
    "username": "zuck"
  }
}

But, if that user had only logged in to your app for the first time after 30th May 2014 (the changeover date), he'd have something like...

{
  "http://facebook.com/4":
  {
    "id": "277123456789101",
    "first_name": "Mark",
    "gender": "male",
    "last_name": "Zuckerberg",
    "link": "https://www.facebook.com/zuck",
    "locale": "en_US",
    "name": "Mark Zuckerberg",
    "username": "zuck"
  }
}

Giving you the 277... app-scoped id for your app.

Unfortunately, doesn't look like this works for 2.0/2.1 (at least not anymore) — Nate, Sep 27 '14 at 16:11
I just successfully make this call using version 2.3 of the Facebook Graph API: https://graph.facebook.com/v2.3?access_token=[KEY]%7C[SECRET]&ids=4 — Raymond Yee, Apr 17 '15 at 18:36

In addition to the comment by @Raymond Yee, you have to provide APP_ID, APP_SECRET and FACEBOOK_USER_ID (note that this is the numeric id, not the username):

So it works with this URL:

https://graph.facebook.com/v2.3?access_token=[APP_ID]%7C[APP_SECRET]&ids=[FACEBOOK_USER_ID]

You have to put user ID, not username!!! Replace FACEBOOK_USER_ID with the numeric id, not with username – Deyan Vitanov Dec 03 '15 at 23:32
