Each Webhook node gives you a Test URL (editor-only) and a Production URL (requires the workflow to be active). Security is built-in: Basic, Header, or JWT auth, plus IP allow-listing and CORS options."

Easy to rotate or share.*\n\n* **JWT Auth** → Caller sends a signed JWT (`Authorization: Bearer <token>`).\n  *Stronger option — tokens can expire and carry claims.*\n\n**Extra hardening (Options menu):**\n\n* **IP Whitelist** → Only allow listed IPs.\n* **Allowed Origins (CORS)** → Restrict browser requests to known domains.\n* **Ignore Bots** → Block crawlers/link previewers."
