Overview
The OneDrive API (part of Microsoft Graph) lets you read, upload, and manage files in a user's OneDrive storage using OAuth 2.0. It supports resumable uploads for large files, real-time webhooks for file change notifications, and sharing link creation for both personal and business accounts. It is particularly useful for apps targeting Microsoft 365 enterprise users who already have OneDrive through their organization.
Beginner Tip
Register your app in the Azure Active Directory portal (portal.azure.com) to get a client ID and secret. Use the Microsoft identity platform OAuth flow to get an access token with Files.ReadWrite scope before making any Drive API calls.
