A webhook is an automated HTTP request one system sends to another when an event happens, used to push data or trigger an action in near real time.

Also known as
web hook; HTTP callback
In a marketing stack, webhooks connect tools without a full integration: a scenario can fire a webhook to notify another system, or an external system can call a webhook to send data in. They are the lightweight glue of event-triggered automation.
In practice
Treat outbound webhooks as something that can fail silently: validate payloads, log them, handle retries, and confirm the receiving system actually acts on the payload. Avoid sending sensitive data unless the destination is approved. A webhook firing into a dead endpoint breaks an automation with no obvious error.
