Save Files to Owner G-Drive(Google Script)

Question

I have a web app created using google script which is distributed in a team,They will use it to upload some files.

I want to save those files into my drive rather than their own accounts.

According to my research I can only save it my account If I publish that app with option Execute as me and option who has access with anonymous.

But I want to Execute as user accessing this app option(that required user to authorized).

Anyone know how to solve this?

Answer 1

Create a service account and enable Domain-wide Delegation of Authority on it. Then you can execute saves to the Google Drive under your account. You'll need to leverage a Google OAuth2 library.

Here's a good one:
