The API reference isn't available right now

This instance couldn't load its API specification. The reference returns as soon as the specification is readable again.

Back to the API reference

No such operation

This instance documents no operation under that identifier. It may have been renamed, or it may belong to a feature this installation hasn't enabled.

Back to the API reference

This reference may be out of date

This instance couldn't reach its API specification on the last attempt, so this page shows the copy fetched before that. Anything added or changed since then is missing here, and the reference updates itself as soon as the specification is readable again. Last fetched 2026-10-22 22:09 UTC.

API reference Notifications

Lists the webhooks sent to your endpoints in a time window.

GET /api/notifications/events deprecated

Requires: Notifications.Events, merchant scope.

Newest first. This is how a receiver that was unavailable discovers what it missed: ask for the window your receiver was down for, narrow to `Failed` or `DeadLettered` if you only want the ones that did not land, and follow the continuation token until it comes back empty. The window is bounded, and a wider one is refused rather than quietly narrowed: on a recovery call, an answer silently missing eleven months would look exactly like a merchant who sent nothing. Read a longer period in steps. Each item is one delivery: an event sent to three of your endpoints is three items with the same `eventId`. Pass `eventId` to read every delivery of one event and see which of your endpoints received it. The bodies are not on this response. Fetch the ones you need individually.

Signed in, you can send this request to your own sandbox merchant from the console and read the answer. Sign in to try it.
