/v4/subscription/webhook/{id}/retry

Retry a failed webhook by re-queueing it for delivery. Only webhooks in the failed state can be retried.

The retry is delivered with the current configuration, not the one used for the original attempt: it goes to the alert's current URL and is signed with the current HMAC secret (unsigned if HMAC was disabled since). To deliver to a different URL or with a different secret, update the alert or the HMAC configuration first, then retry.
