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. If you want to send a webhook when an action occurs in an app, learn how to send webhooks in Zaps.

- 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 with 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. The only way to know if a URL is live is to visit the editor and look at the URL (which never changes for a Zap). There is no way to customize the response to the request you send to the Catch Hook URL, as the response is sent before the Zap triggers and runs on the webhook request.
