Webhook Trigger: how workflows really get triggered by the outside world
After Schedule Triggers, the next foundation is Webhook.
A Webhook answers a different question:
“What event starts this workflow?”
In this manual, I covered:
- What a Webhook Trigger actually does (and what it doesn’t)
- GET webhook behavior (browser, curl, external tools)
- Test URL vs Production URL
- What n8n really receives as input
- Verifying execution using curl
No advanced security yet.
No overengineering.
Just understanding how events enter n8n correctly.
If you understand Webhooks, integrations stop feeling “magical” and start feeling predictable.
