Plain-language definition
Plain-language definition
An HTTP message sent automatically when an event occurs.
Why it matters
Webhooks let systems react promptly without constant polling, but deliveries can be duplicated or delayed.
Technical detail
A webhook delivers an event payload to a registered endpoint and requires authentication or signature verification, replay protection, retries, and idempotent handling.
Examples
- A payment provider sends a signed webhook when a dispute opens.
