Replaying a key answers `200` with the delivery the first call made. # Errors `400` without `Idempotency-Key`, `401`, `403` without `WEBHOOKS_MANAGE`, `404` for an unknown or another tenant's delivery, `409` when the endpoint is disabled or gone (`WEBHOOK_ENDPOINT_DISABLED`, `WEBHOOK_ENDPOINT_MISSING`), when the key is held by a request still running (`RESEND_IN_PROGRESS`) or was used for a different delivery (`IDEMPOTENCY_KEY_REUSED`), `503` when a store cannot be reached. ## OpenAPI ````yaml /openapi.json post /v1/webhooks/deliveries/{delivery_id}/resend openapi: 3.1.0 info: title: Esectra API description: >- Transaction screening, identity verification, and wallet risk. Every create route accepts `Idempotency-Key`; replaying one returns the original record with `200` where the first call returned `201`. `POST /v1/transactions` requires the header, because a duplicated transaction is a duplicated financial record. license: name: proprietary identifier: proprietary version: 0.1.0 servers: [] security: [] paths: /v1/webhooks/deliveries/{delivery_id}/resend: post: tags: - Webhooks summary: Handles `POST /v1/webhooks/deliveries/{delivery_id}/resend`. description: >- Sends the delivery's event again as a new delivery. `Idempotency-Key` is required: a resend is a side effect on a customer's system, and a double click or a retried request must produce one delivery, not two.
