How can I use google drive api to find by whom a file was shared

Question

I know I can use the file permissions to see with who a file was shared with, but how can use the api to find who was the user that shared the file?

Answer 1

You cant. When a file is shared who did the sharing is not abaliable.

Anyone with access to the file can technically share it. There are a few exceptions with who you can share a file to if the file is part of a domain or a group.

So there is really no way of knowing who did the sharing.

this is true with both the google drive web app and with the api.
