Get folder and files Google Drive API with Shared Device and Service Account

Question

I'm working with a Google Service Account, I have access to Google Drive API and a Shared Unit.

I need to get access to all the files and folders from a Shared Unit. I tried a lot of different ways to do this.

drive_service.files().list(
    q = f"'{parent_folder}' in parents",
    spaces = 'drive',
    supportsTeamDrives=True
).execute()

>> {'kind': 'drive#fileList', 'incompleteSearch': False, 'files': []}

drive_service.files().list(
    q = f" parents in '{parent_folder}'",
    spaces = 'drive',
    supportsTeamDrives=True
).execute()

>> {'kind': 'drive#fileList', 'incompleteSearch': False, 'files': []}

drive_service.files().list(
    spaces = 'drive',
    supportsTeamDrives=True
).execute()

>> {'kind': 'drive#fileList', 'incompleteSearch': False, 'files': []}

drive_service.drives().list().execute()

>> {'kind': 'drive#driveList',
 'drives': [{'kind': 'drive#drive',
   'id': '0AOELwkzr21lFUk9VA',
   'name': 'foo'}]}

I know a have access because I can upload files to the parent folder. Also, there are files in the parent folder.

Do you have any clue?

Thank you for your time

Answer 1

I figure it out.

An additional parameter had to be passed:

includeItemsFromAllDrives = True,
supportsAllDrives = True

This works:

drive_service.files().list(
    q = f"'{parent_folder}' in parents",
    spaces = 'drive',
    includeItemsFromAllDrives = True,
    supportsAllDrives = True
).execute()
