# Resend a failed webhook delivery

> Queues a fresh attempt with the 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. The new attempt uses the webhook's current URL, topic, and headers.
