It is retried like any other delivery, and its attempts are listed with `"replay": true`. Your receiver deduplicates on the event id, so replaying an event it already processed changes nothing. The endpoint must be verified (409 `webhook_endpoint_unverified` otherwise), and an event that is not in the endpoint's log answers 404. Each call sends the event again. Requires the `webhooks` scope. ## OpenAPI ````yaml /openapi.json post /v1/webhooks/{endpoint_id}/deliveries/{event_id}/replay openapi: 3.1.0 info: title: NoResponse API version: '1' description: >- The NoResponse API assesses a signup, login or purchase and answers with the account's one current risk: a 0 to 100 score, a decision for the flow (`allow`, `step_up`, `review` or `block`), the reasons behind it and the decision for each flow. The assessment's own facts, such as its status, confidence and incomplete sources, sit under `detail`. Authenticate every request with your API key as `Authorization: Bearer nrk_...`. Call the API only from your backend. Guides, SDKs and webhook verification are at [docs.noresponse.org](https://docs.noresponse.org/).

A key is `nrk_live_` or `nrk_test_`, a 26-character key id, `_` and a 43-character secret. A key sees only its own environment's data. Each key has one or more scopes: `assess` creates and reads assessments, records outcomes and reports key usage; `history` reads assessments, an account's current risk and an account's history, and erases an account; `detailed` adds the detailed view; `webhooks` registers, tests, rotates and deletes webhook endpoints; `integrations` registers and manages hosted provider integrations. A missing, unknown, revoked or expired key answers 401. A valid key without the scope an operation needs answers 403. ```` This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
