# Replay a delivery

URL: https://docs.healthcare.dev/reference/webhooks/replay-a-delivery

```http
POST https://api.healthcare.dev/v1/webhooks/{id}/deliveries/{delivery}/replay
```

Pro plan and up (403 `plan-upgrade-required` below Pro); never counts as a billable call. Send a delivery's event again now, as a new delivery with its own retries. The event `id` (`Hdev-Webhook-Id`) and body are unchanged, so your endpoint can recognize a repeat. Not while the original or an earlier replay of it is still queued, at most 10 replays per delivery, and only to an active webhook (409).

Requires an API key: `Authorization: Bearer hdev_live_...`. See [Authentication](/authentication).

## Errors

Errors are `application/problem+json` ([RFC 9457](https://www.rfc-editor.org/rfc/rfc9457)). Branch on `type`, not on `title`. See [Errors](/errors).

| Status | `type` | When |
| --- | --- | --- |
| 400 | `invalid-request` | A parameter or the body failed validation; `errors` lists each field. |
| 401 | `unauthorized` | Missing, malformed or revoked API key. |
| 403 | `plan-upgrade-required` | The plan doesn't include this feature; `required_plan` names the plan that does. |
| 404 | `not-found` | No record with that id (retired records are still returned). |
| 409 |  | Still retrying, or the webhook is disabled |
| 429 | `rate-limited / quota-exceeded` | Too many requests per second (retry after `Retry-After`), or the monthly quota is used up. |
