Resend a delivery
Issue a NEW delivery (new id, resend_seq+1) of the same event payload to the same endpoint, leaving the original delivery untouched. Useful for replaying a delivered webhook on demand or verifying consumer dedup. Only terminal deliveries (DELIVERED or FAILED) can be resent, and the endpoint must be active. The new delivery starts PENDING and is dispatched on the normal path (in SQS mode it may take up to ~30s to be enqueued).
id and an incremented resend_seq. The source delivery is left untouched, so the full history of every attempt is preserved.
Only deliveries in a terminal status (DELIVERED or FAILED) can be resent, and the endpoint must be active. Resending a PENDING or SENDING delivery returns 409 Conflict with code not_resendable; resending to a disabled or archived endpoint returns 409 Conflict with code endpoint_not_active.
