Overview

Stop sending sensitive agency drafts as permanent email attachments. This workflow creates a "self-destructing" delivery system that hosts files via UploadToURL, sends branded previews via SendGrid, and automatically expires access after a set duration while logging the entire lifecycle in Google Sheets.

🎯 What This Workflow Does

Turns any sensitive file into a professional, time-limited client preview:

Sync SharePoint to Google Drive via Supabase (n8n Workflow)

Eliminate manual file transfers and data silos with this enterprise-grade synchronization pipeline. This n8n workflow automates the heavy lifting of mirroring your Microsoft SharePoint document libraries to Google Drive while maintaining a robust audit trail in Supabase or Postgres. Designed for high-reliability environments, the automation utilizes a sophisticated delta-check logic: it fetches SharePoint metadata, compares it against your existing database records using the 'Compare Datasets' node, and identifies only new or modified files for processing. By leveraging the 'Split in Batches' node, the system handles large volumes of data without hitting memory limits, ensuring every document is securely downloaded via HTTP and re-uploaded to its destination. Once the transfer is verified, the workflow updates your database status in real-time, providing a transparent log of your synchronization history. This is an essential solution for organizations transitioning between cloud ecosystems or those requiring a redundant, cross-platform backup strategy. It effectively bridges the gap between Microsoft and Google ecosystems using Supabase as a high-performance state-management layer. **Common Use Cases:** - Automated Multi-Cloud Disaster Recovery: Maintain a real-time mirror of critical SharePoint corporate assets in Google Drive to ensure business continuity during service outages. - Cross-Departmental Collaboration: Automatically sync project documentation from an executive SharePoint site to a creative team's Google Drive folder for seamless cross-platform access. - Centralized Document Auditing: Use Supabase to track every file movement between ecosystems, creating a searchable metadata index for compliance and regulatory reporting.
