Drupal ↔ SharePoint Document Library Connector

Overview

The Drupal SharePoint Document Library Connector provides a powerful bridge between your Drupal content management system and SharePoint Online. This integration enables content editors to access, manage, and embed SharePoint documents directly within Drupal while maintaining SharePoint’s robust permission and versioning systems.

Features

• Bi-directional file synchronization
• Custom Media field widget for SharePoint files
• Drupal Views integration for document listings
• SharePoint permission mapping to Drupal roles
• Document version control and history
• Metadata synchronization
• Search integration with SharePoint search
• Real-time webhook notifications for file changes

Technical Details

Technologies: Microsoft Graph API, SharePoint REST API, Drupal Media module, Drupal Field API, Drupal Views, OAuth 2.0

Requirements:

• Drupal 9.x or 10.x with Media module
• SharePoint Online subscription
• Azure AD app registration with Graph API permissions
