n8n Webhook Node: Master from Basics to 10 Practical Examples

D: 🚀 Automation just got easier! The n8n Webhook Node is your gateway to seamless integrations, real-time data processing, and event-driven workflows. Whether you’re a beginner or a pro, this guide will take you from zero to hero with clear explanations and hands-on examples.

🔍 What is a Webhook Node in n8n?

A Webhook is like a digital doorbell 🛎️—it listens for HTTP requests (GET/POST/PUT) and triggers your workflow when data arrives. In n8n, the Webhook Node acts as an endpoint to:

• Receive data from external apps (Slack, GitHub, Shopify).
• Process real-time events (e.g., form submissions, payments).
• Avoid polling APIs manually (saves time! ⏳).

Key Features:
✅ Dynamic URL Generation – Unique endpoints per workflow.
✅ Method Support – GET, POST, PUT, DELETE.
✅ Security – Optional authentication (Basic Auth, Headers).

🛠️ How to Set Up a Webhook Node

1. Add the Node: Drag the Webhook node into your workflow.
2. Configure:
   • Choose HTTP Method (e.g., POST for form data).
   • Enable Respond with Webhook to send replies (e.g., confirmation message).
3. Test: Use tools like Postman or curl to send a request:

   curl -X POST https://your-n8n-url/webhook-path -d '{"key":"value"}'
