Webhook Deliveries

Retry a webhook delivery

Queue an immediate retry of this delivery. The delivery is marked pending, its attempt count is reset to 0 and next_retry_at is set to now, and it is queued for delivery at once. Calling retry on an already-pending delivery queues it again. Failed and dead-lettered deliveries can be retried; a delivery that already succeeded cannot (409 already_succeeded).

POST/webhook-deliveries/{id}/retry

Common errors

  • 404 resource_missing — the referenced resource does not exist or is not visible to your key.
  • 409 conflict — Idempotency-Key collision with a different body, or a concurrent state-transition conflict.

Idempotency

Pass an Idempotency-Key header (UUID v4 recommended) to make retries safe. Keys are valid for 24 hours; see the idempotency guide.

Authorization

x-api-key<token>

Your RevKeen merchant API key. Create and manage keys in Dashboard → Settings → Developer. Use rk_sandbox_* for staging/test and rk_live_* for production. The same key may be sent as Authorization: Bearer <key> if that suits your HTTP client better. A missing, invalid, expired, or revoked key returns 401 with a WWW-Authenticate: Bearer challenge; a valid key without the required scope returns 403.
