GET /api/notifications/events deprecated

Requires: Notifications.Events, merchant scope.

Requires API key scope: webhooks ()

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.

429 Too Many Requests

The request was refused because a rate limit was exceeded, or because something a later retry can clear stopped it. A rate limit refusal carries an `application/problem+json` body: wait at least the interval `Retry-After` names before retrying, then back off. Limits are tuned per deployment, so read the allowance from the response headers rather than assuming a fixed ceiling. Any other refusal carries the standard error envelope as `application/json`, and its `error.code` names the cause.
