Access all domain users' file in Office365 OneDrive

I need to access all users' files in a domain via REST API. I could only access the domain user's files via access token granted via normal OAUTH flow.

I found this article: Building Daemon or Service Apps with Office 365 Mail, Calendar, and Contacts APIs (OAuth2 client credential flow)

This article mentions only Mail, Calendar, and Contacts API. Is File API supported?

This is what worked for me:

  1. Create an access_token as described here https://graph.microsoft.io/en-us/docs/authorization/app_only and use it in the next steps in the Authorization header
  2. Get all the users using this REST API: https://graph.microsoft.com/v1.0/users
  3. Iterate through the users and get their files with this API (adding their userPrincipalName in the url): https://graph.microsoft.com/v1.0/users/[email protected]/drive/root/children
