OneDrive API Integration (via Microsoft Graph)

OAuth Setup

• Use OAuth 2.0 with Microsoft Identity Platform
• Microsoft Graph base URL: https://graph.microsoft.com/v1.0
• Required scopes:
  • Files.Read - Read user's files
  • Files.Read.All - Read all files user can access
  • Files.ReadWrite - Read and write user's files
  • User.Read - Read user profile
  • offline_access - Refresh tokens for long-lived access

Key Endpoints

• GET /me/drive - Get current user's OneDrive
• GET /me/drive/root/children - List items in root folder
• GET /me/drive/items/{item-id} - Get item metadata
• GET /me/drive/items/{item-id}/children - List folder contents
• GET /me/drive/root:/{path} - Access items by path
• GET /me/drive/items/{item-id}/content - Download file content
• GET /drives/{drive-id}/items/{item-id} - Access shared drives
• GET /me/drive/items/{item-id}/delta - Track changes (delta sync)
• POST /subscriptions - Create webhook subscriptions for change notifications

Core Resources

• Drive - Logical container of files (document library or user's OneDrive)
• DriveItem - Item within a drive (document, photo, video, folder)

Events to Track

1. Files - File created, modified, renamed, deleted, moved
2. Folders - Folder created, renamed, deleted, reorganized
3. Sharing - Files shared, permissions changed
4. Versions - File version history changes
5. Sync Activity - Delta changes for incremental sync

Implementation Tasks

• Set up basic integration structure following integrations/github/src/index.ts pattern
• Implement OAuth 2.0 flow with Microsoft Identity Platform in account-create.ts
• Create API utilities in utils.ts for Microsoft Graph API
• Implement sync logic in schedule.ts using delta queries for incremental sync
• Set up webhook subscriptions for real-time change notifications
• Convert OneDrive events to CORE activity format
• Add error handling and rate limiting
• Create integration documentation
• Add to integrations/README.md

Technical Notes

• OneDrive is accessed through the Microsoft Graph API, not a standalone API
• URL pattern: https://graph.microsoft.com/v1.0/{root-resource}/{onedrive-resource}
• Delta queries (/delta endpoint) enable efficient incremental sync
• Webhook subscriptions require a publicly accessible notification URL
• Both personal OneDrive and OneDrive for Business are supported
• The same API can access SharePoint document libraries

• Working with Files in Microsoft Graph
• OneDrive REST API Getting Started
• OneDrive API Docs (GitHub)
• Microsoft Graph API - Get Drive

Labels

enhancement, integration, new-feature

Start by comparing integrations/google-docs/, integrations/google-sheets/, and integrations/github/src/index.ts, then map the required files under integrations/onedrive/. Review the Microsoft Graph OAuth, delta, and subscription requirements before implementing. Done means the listed OAuth, sync, webhook, activity, error-handling, documentation, and integrations/README.md tasks are complete.
