# Retry a webhook delivery

`POST /v1/webhook-endpoints/{endpoint_id}/deliveries/{delivery_id}:retry` · permission `webhook-endpoints:write` · all plans

Queues a `succeeded` or `abandoned` delivery of the last 30 days again as a new delivery of the same event and returns the new delivery. The new delivery keeps the event's `webhook-id` and has `replay_no` one higher. A delivery that is still `pending` or `retrying` is retried by the schedule and cannot be retried by hand. The body is optional; when given it is an empty object.

## Request

| Field | Type | Required | Description |
|---|---|---|---|
| `endpoint_id` | path | yes | Webhook endpoint ID (`whe_…`). |
| `delivery_id` | path | yes | Delivery ID (`whd_…`). |
| `Idempotency-Key` | header | no | Replays the response for a repeated request with the same key, without queueing again. |

## Response

`200 OK` with the new delivery.
