# Webhook replay

> Understand the coming-soon replay action on webhook delivery attempts.

Webhook delivery attempts show a **Replay** action. It is visible as a coming-soon control and is not available yet.

## What it will be for

Replay will send a retained webhook payload to the subscription endpoint again. It is intended for cases where your endpoint was fixed after a failed delivery.

## What to use now

* Use delivery attempts to inspect status, latency, retry count, and response preview.
* Fetch retained payloads while they are available.
* Copy the request as cURL from the delivery detail view when payload data is loaded.
* Use **Send test** to confirm the endpoint is healthy.

## What happens next

There is no setup action or release date. Keep endpoints idempotent now so replay is safe when it becomes available.
