Is it possible to use OneDrive Business API with App Only Token for Daemon Apps?
I have tried technique purposed in this post, but i couldnt access API. In fact there is nothing in OneDrive Business API documentation which indicates how to impersonate tenant users, for example /drives/{upn}/root or something.
Best,
It does work with app only tokens for daemon apps. You can use the user's UPN as the drive-id, as you mentioned in your question. We're getting the documentation updated to include that this works.
