How to secure GET Webhooks? What are webhooks?

Webhooks are special URLs that instantly trigger workflows when they receive an incoming HTTP request (like GET or POST). They're perfect for connecting external tools to n8n in real time.

๐Ÿ” Why webhooks should be protected Unprotected webhooks are publicly accessible on the internet โ€” anyone with the link can trigger your workflow. This can lead to spam, unwanted requests, or even data loss.

โœ… Best Practice: Use built-in Authentication n8n provi
