How to get a link to a user's Facebook profile?

Question

JavaScript

I use Facebook login on my site. Upon successful authorization, the user id is returned, which previously could be substituted into the address bar on Facebook and open the profile of this user. For some time now, only a part of accounts have been opened in this way, most have written that the content is not available. How can i fix this??
I can't find anything useful in their API

Answer 1

Yes, now Api returns not the user ID but the authorization ID and now it is impossible to get a link to the user account. At least since July 2018, it has become so.
You can try getting permission to:
user_link - Allows access to the app's user profile URL on Facebook.
