Step 3: Connect OpenClaw to n8n
Method A: Webhook (Simple)
python
# In OpenClaw, call n8n webhook
import requests
n8n_webhook_url = "https://n8n.yourdomain/webhook/abc123"
data = {
"message": "New task from user",
"sender": "user@example.com",
"priority": "high"
}
response = requests.post(n8n_webhook_url, json=data)
Method B: n8n Node (Advanced)
text
┌─────────────────────────────────────────────────────────┐
│ n8n HTTP Request Node │
│ │
│ Method: POST │
│ URL: https://api.openclaw.ai/v1/execute │
│ Headers: │

Security Best Practices
text
┌─────────────────────────────────────────────────────────┐
│ SECURITY LAYER │
│ │
│ 1. API KEYS (n8n Credentials) │
│ └─► Encrypted storage │
│ └─► Never expose in workflows │
│ │
│ 2. WEBHOOK SECURITY │
│ └─► Use random URLs │
│ └─► Add authentication headers │
│ └─► IP whitelist │
│ │
│ 3. DATA FLOW │
│ └─► Validate all inputs │
│ └─► Sanitize before sending to APIs │
│ └─► Log for audit │
│ │
│ 4. ACCESS CONTROL │
│ └─► Restrict n8n dashboard access │
│ └─► Use strong passwords │
│ └─► Enable 2FA │
└─────────────────────────────────────────────────────────┘
Troubleshooting
Webhook Not Triggering?
text
✓ Check URL is correct
✓ Verify workflow is "Active"
✓ Check n8n execution logs
✓ Test with curl:
curl -X POST https://n8n.yourdomain/webhook/xxx \
-H "Content-Type: application/json" \
-d '{"test":"data"}'
Authentication Errors?
text
✓ Re-connect credentials in n8n
✓ Check API scopes/permissions
✓ Verify token not expired
✓ Check service status page
Data Not Passing?
text
✓ Check field names match
✓ Verify data types (string vs number)
✓ Use "Set" node to transform data
✓ Add "Function" node for custom logic
Quick Reference
Next Steps
- Install n8n (self-host or cloud)
- Create first workflow (webhook → email)
- Connect OpenClaw (call webhook from agent)
- Build complex flows (multi-step automations)
- Monitor & optimize (check execution logs)
