# An event catalog for every webhook

- Date: 2026-10-25
- Type: New
- Surface: Webhooks, Developer portal and CLI
- What you need to do: Nothing.
- Address: https://developers.rivr.io/changelog/2026-10-25-webhook-event-catalog

The page /events lists every webhook Rivr sends: when it is sent, the body's fields with their types and an example, whether it is signed and with which header, and which guide shows it. It covers the order's events (Created, Pending, Completed, Cancelled and Refunded) on the order's callbackUrl, the clinic's webhook address and your organisation's endpoints, and the MerchantOnboarding notification. It also says what differs from the API's own answers: status is a string in the webhook but a number in GET, and the payment method is grouped differently in the two. The same catalog is at /events.md and, for machines, at /events.json.
