What a webhook is
A webhook is an HTTP request one system sends to a URL you provide when something happens, such as a booking or form entry. It replaces polling for changes.
Receiving them
Make, n8n and Zapier can each provide a webhook URL that starts a workflow. Slack incoming webhooks work the other way: your workflow posts into Slack.
Securing and testing
- Treat webhook URLs as secrets
- Verify signatures or a shared header when the sender supports it
- Expect retries and duplicates; make the workflow idempotent
- Test with sample payloads before connecting real data
