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: 📝 Captures Delivery Request - Receives the file (binary or URL), recipient info, and desired expiry duration (e.g., 24 hours) via Webhook. ☁️ Instant CDN Hosting - UploadToURL hosts the asset and returns a high-speed public link. 🔑 Secure Token Generation - Generates a unique hex token and calculates the exact UTC expiry timestamp. 📊 Real-time Logging - Records the link in Google Sheets as active with all metadata before the email is sent. 📧 Branded Delivery - Sends a professional HTML email via SendGrid featuring your branding, a secure "View File" button, and a clear expiry notice. ⏳ Automated Expiration - Pauses execution for the specified duration using the Wait node, then updates the sheet to expired and notifies both the client and the agency. ✨ Key Features UploadToURL Integration**: Native community node hosting ensures your files are web-ready instantly without manual cloud storage setup. Dynamic "Burner" Logic**: The link stays active only as long as you specify (from 1 to 168 hours). Dual-Phase Notifications**: Clients get a polite notice when the link is active and a second one when it has officially expired. Lifecycle Tracking**: A centralized Google Sheet acts as your "Delivery Command Center," tracking tokens, sent times, and expiry statuses. Agency Audit Trail**: The agency receives a final summary email once a link's lifecycle is complete, providing a full record for project management. 💼 Perfect For Creative Agencies**: Sharing draft designs, videos, or proposals that shouldn't live in a client's inbox forever. Legal & Finance**: Providing temporary access to sensitive documents or statements. Freelancers**: Delivering final assets that require a "preview-only" window before final payment. HR Teams**: Sending temporary access to employee handbooks or internal policy drafts. 🔧 What You'll Need Required Integrations UploadToURL** - To host assets and provide secure CDN links. n8n Community Node** - n8n-nodes-uploadtourl must be installed. SendGrid** - To send the branded preview and expiry emails. Google Sheets** - To act as the database for link tracking. Configuration Variables GSHEET_SPREADSHEET_ID: The ID of your tracking sheet. DEFAULT_EXPIRY_HOURS: Default time (e.g., 24) if not specified in the webhook. AGENCY_NAME & AGENCY_EMAIL: For branding the automated emails. 🚀 Quick Start Import Template - Copy the JSON and import it into your n8n canvas. Install Node - Ensure the UploadToURL community node is installed. Set Credentials - Link your UploadToURL, SendGrid, and Google Sheets accounts. Prepare Sheet - Create a sheet named BurnerLinks with columns: Token, Recipient Email, Status, Sent At, Expires At, and CDN URL. Define Variables - Update the n8n variables with your Sheet ID and Agency details. Deploy - Activate the workflow and start sending secure, timed previews. 🎨 Customization Options Branding**: Edit the Generate Link Record code node to update the HTML/CSS for the email templates to match your brand colors. Extended Wait**: For links lasting weeks, ensure your n8n instance is configured to persist executions across restarts. Slack Alerts**: Add a Slack node to notify your team the moment a client clicks the link (requires a redirect/tracking layer). Password Protection**: Integrate an additional layer that requires a password (sent via a separate channel) to view the UploadToURL link. 📈 Expected Results Enhanced Security**: Sensitive files no longer float around indefinitely in client inboxes. Professional Impression**: Clients receive branded, structured previews that emphasize security and professionalism. Zero Manual Cleanup**: No need to manually delete files or remember to "turn off" links. Complete Transparency**: Always know exactly which links are active and when they were accessed. 🏆 Use Cases Pitch Deck Delivery Send your high-stakes pitch deck with a 48-hour window. The urgency encourages the client to review it promptly while protecting your IP. Contract Previews Share a draft agreement for a quick 24-hour review. Once the window closes, the client is prompted to contact you for the final version. Limited-Time Portfolio Share a custom portfolio or "lookbook" with a lead, giving them 7 days of access to create a "limited time" feel to your availability. 💡 Pro Tips Wait Node Execution**: Each link runs as a separate execution. If you send 100 links, you will see 100 "Waiting" executions in your history. File Types**: The workflow includes validation for PDF, JPG, PNG, DOCX, and MP4. You can expand this in the Validate Payload code node. BCC Records**: The workflow automatically BCCs the agency on the first email so you have a copy in your own sent folder.
