Bridge Public Webhooks to Your Local n8n—Without Punching Holes in Your Firewall

Receive webhooks securely in the cloud and relay them into your local n8n workflows—even if you’re behind NAT or a corporate firewall. This workflow uses webhook.site as a temporary public endpoint and pipes incoming requests into your private infrastructure. No custom relay services needed. No port-forwarding headaches.

Why This Workflow Belongs in Your Stack

✅ Eliminate Port Forwarding Hassles
Avoid exposing your local machine to the internet just to accept webhooks. Stay secure while integrating external services.

✅ Secure and Controlled Integration
Run external integrations safely without compromising your local environment or opening firewall ports.

✅ Plug-and-Play Deployment
Use right away for public-to-local relay. Includes clear JSON nodes and documentation for rapid deployment.

✅ Modular and Adaptable
Customizable for GET requests, different payload formats, or more complex relay logic.

What This Workflow Does

• Runs on a scheduled interval (default every 10 seconds)
• Retrieves a secure token from webhook.site
• Checks webhook.site for any new incoming requests
• Filters out requests already processed
• Forwards new POST requests to your local n8n webhook
• Stores the last processed timestamp to prevent duplicates

Tech Stack Highlights

• n8n (self-hosted or cloud)
• webhook.site for public-facing webhooks
• Optional @horka.tv/n8n-nodes-storage-kv for local token storage
• JSON-based node configuration
• No-code customizable workflow

Perfect For

✅ Developers running n8n locally or behind a firewall
✅ SaaS teams needing secure integrations without exposing internal servers
✅ Businesses wanting quick proof-of-concept external integrations
✅ Anyone tired of managing tunnels for webhook testing

Skip building your own relay service or struggling with networking setups. This workflow lets you connect cloud apps to your local n8n in minutes. Save dev time, keep your servers private, and maintain full control of incoming requests.
