I'm trying to create script to download all files from another user shared folder in google drive using rest api. If i'm right, there are two variants:
But both of this variants returning only files which were once opened by my google account in browser. If I open file in browser - this file will appear in results of API calls.
Folder is shared for anyone, who has link.
Where is the problem, how I can list all files in folder?
Since you did not give us any info about the SCOPE, I am wild-guessing that it may be your problem. You probably have FILE scope, instead of DRIVE.
Also, I would recommend to test these things with 'TryIt!' here. You can quickly modify both scopes and queries there.
Good Luck
