# Resend failed webhook deliveries

> Queues fresh attempts with each failed delivery's original data and meta. If next_retry_at is in the future, an automatic retry is still scheduled, so a manual resend may deliver the webhook twice. Receivers must handle duplicates. New attempts use each webhook's current URL, topic, and headers.
