RESTwebhooks is a design pattern in which an application publishes events and other systems subscribe by providing an HTTP endpoint. When an event occurs, the publisher sends an HTTP request to the subscriber’s RESTful endpoint, typically using POST. The payload carries information about the event and a reference to the affected resource. RESTwebhooks emphasize lightweight, language-agnostic integration and alignment with REST conventions.
In a typical flow, a publisher registers one or more callback URLs with a subscriber or middleware.
Payload formats and security: Most RESTwebhooks use JSON payloads with fields such as event, id, timestamp,
Reliability and best practices: HTTP-based delivery is typically best-effort; publishers may retry failed deliveries with exponential
