POST /v1/webhooks/{id}/deliveries/{deliveryId}/retry — Retry a Delivery
Re-arm a failed delivery with a fresh attempt budget and an immediate first try.
POST
Retry a failed delivery
The replay path for events lost to an outage on your side: re-queues a delivery that exhausted its retries, resetting the attempt counter so it gets the full ladder again rather than one attempt at the far end of it.
A delivery that already succeeded returns
409 already_delivered.
