Webhooks are automated messages sent between apps—a type of notification that includes detailed information about new items in apps. If you're on a paid plan, you can trigger Zaps from webhooks. You can also send a webhook when an event occurs in an app.

Limitations
- Zapier cannot 301 or 302 redirect you to a different URL and deliver/retrieve payloads from the new address.
- Zapier will always return a success message and a payload of debugging information when collecting a webhook, regardless of whether there is a Zap behind the webhook or if it is paused or not. To find out if a URL is live, visit the Zap editor and look at the webhook URL (which is always the same for a Zap).
- Although it's not possible to customize this response, you can remove it completely by using Silent Mode.
