🔹 What Are Webhooks?

Webhooks are user-defined HTTP callbacks that allow apps to send real-time notifications when specific events occur. Unlike APIs (which require polling), webhooks push data instantly, making them ideal for automation.

Webhook vs. API Polling

Example:

• A payment gateway (Stripe) sends a webhook to N8N when a transaction succeeds.
• N8N processes the data and updates your CRM (HubSpot) automatically.

🔹 Setting Up Webhook Nodes in N8N

N8N supports multiple webhook types:

1. Webhook Node (GET/POST) – For standard HTTP requests.
2. Wait Node – Pauses workflows until a webhook is received.
3. Webhook-Enabled Triggers – Start workflows via external calls.

Step-by-Step: Creating a Webhook Workflow

1. Add a Webhook Node

   • Drag the Webhook node into your workflow.
   • Choose HTTP Method (GET/POST).
   • Copy the Webhook URL (e.g., https://your-n8n.io/webhook/123).

2. Configure the Webhook

   • Set Authentication (Basic Auth, Header Auth).
   • Define Response Data (JSON/XML).

3. Test the Webhook

   • Use Postman or curl to send a sample payload:

     curl -X POST https://your-n8n.io/webhook/123 -d '{"status":"success"}'  

4. Process the Data

   • Connect the Webhook node to Function nodes or apps like Slack, Google Sheets.

🔹 Real-World Use Cases

1. E-Commerce Automation 🛒

• Trigger: New order in Shopify → Action: Update inventory in Airtable.
• N8N Setup:
  • Shopify sends a POST webhook to N8N.
  • N8N parses the order data and syncs it with Airtable.

2. Slack Notifications for GitHub Events 💬

• Trigger: GitHub PR merged → Action: Post in Slack.
• N8N Setup:
  • GitHub webhook → N8N → Slack message.

3. CRM Lead Processing 📊

• Trigger: New lead in Typeform → Action: Add to HubSpot.
• N8N Setup:
  • Typeform webhook → N8N → HubSpot API.

🔹 Best Practices for N8N Webhooks

✅ Use HTTPS – Always secure webhook URLs.
✅ Validate Payloads – Check data integrity (e.g., with HMAC).
✅ Rate Limiting – Avoid spam with Wait nodes.
✅ Error Handling – Add Error Trigger nodes for failed webhooks.
