# Resend a delivery
Source: https://www.desktopaccountingapi.com/docs/api/reference/operations/webhookendpointsresenddelivery/

`POST https://api.desktopaccountingapi.com/v1/webhook-endpoints/{id}/deliveries/{deliveryId}/resend`

Operation ID: `webhookEndpoints.resendDelivery`. Tag: Webhooks.

Delivers the same event (same `webhook-id`, so receivers can deduplicate) once more now, and records the attempt on the delivery. Use it after fixing an endpoint whose deliveries failed.

Authentication: `Authorization: Bearer <secret key>`.

## Path parameters

- `id` (string, required): Unique identifier for the webhook endpoint. example `whe_01j9x4m6v4c8k2t7q0r5s3w1zg`.
- `deliveryId` (string, required): Unique identifier for the delivery of one event to one endpoint. example `whd_01j9x4m6v4c8k2t7q0r5s3w1zj`.

## Headers

- `Idempotency-Key` (string): Makes a write safe to retry. Repeating a key with the same request attaches to or replays the original instead of creating a second one. 1–255 printable ASCII characters, retained 7 days. Reusing a key with a different request returns `422 IDEMPOTENCY_KEY_REUSED`. 1–255 characters; example `6f1c2a0e-1f7e-4c55-9a7a-0b2d2c9e3a10`.
