n8n-ngrok tunnel Setup Script

A very simple PowerShell script that automates the process of starting n8n with ngrok tunneling.

Prerequisites

• ngrok installed and authenticated
• Node.js and npx installed
• n8n installed globally or available via npx

Usage

1. Start ngrok in a terminal:

   ngrok http 5678
   

2. Run the PowerShell script in another terminal:

   .\start.ps1
   

3. When prompted for the ngrok API URL, press Enter to use the default (http://localhost:4040/api/tunnels)

What it does

The script will:

• Verify that ngrok is running
• Fetch the public HTTPS URL from ngrok's local API
• Set the WEBHOOK_URL environment variable automatically
• Start n8n using npx n8n

Notes

• Only runs in windows!
• The script expects ngrok to already be running before execution
• ngrok will continue running after the script terminates
• Press Ctrl+C to stop n8n when finished
