# Redeliver Webhook

> Manually re-attempt a delivery for an existing event

## Overview

Queues a new delivery attempt for the same underlying event as the original delivery. The new
attempt carries a fresh `webhook-timestamp` (so freshness checks on your side pass) and a new
`delivery_attempt_id`, but the same `webhook-id` as the original, so your handler can still
dedupe on it. This endpoint is billable.

Requires the `portfolios:manage` scope.

## Only terminal deliveries are redeliverable

Redelivery is accepted only when the delivery's automatic retry chain has
reached a **terminal** state: `delivered`, `exhausted`, or a `failed`
attempt with no scheduled retry. If the chain is still live — the attempt
is `pending`, or `failed` with an automatic retry still scheduled — the
request returns **409** with error type `redelivery_conflict`. The
automatic retry schedule (7 attempts over \~24 hours) is already working
that delivery; redelivering mid-chain would race it. Poll
[`GET /v1/webhooks/{id}/deliveries/{did}`](/api-reference/monitoring/webhooks/retrieve-delivery)
until the attempt is terminal, then redeliver.

Repeated redelivery of the same terminal attempt is idempotent: the API
returns the existing queued attempt's `delivery_attempt_id` instead of
creating a duplicate.

## Path Parameters

<ParamField path="id" type="string" required>Endpoint ID (`whk_*`).</ParamField>
<ParamField path="did" type="string" required>Original delivery attempt UUID.</ParamField>

## Response

<ResponseField name="object" type="string">Always `"webhook_redelivery"`.</ResponseField>
<ResponseField name="delivery_attempt_id" type="string">UUID of the newly queued attempt.</ResponseField>
<ResponseField name="request_id" type="string">Request identifier.</ResponseField>

## Errors
