Cloud Storage & File Sharing — entry 011 of 18
OneDrive
OneDrive's API, served through Microsoft Graph, lets applications read, write, and share files and folders in a user's personal or organizational OneDrive. A live GET against the real gateway, graph.microsoft.com/v1.0/me/drive, returned a 401 without a token, reconfirming OAuth 2.0 auth over HTTPS, and a follow-up OPTIONS preflight returned Access-Control-Allow-Origin: *, resolving cors from unknown to yes. Personal Microsoft accounts get 5GB free, with paid Microsoft 365 subscriptions raising the storage cap substantially.
