Webhook Delivery
Batch classification (classify batch) and sound alerts (alerts on) use webhook callbacks for asynchronous result delivery. The OpenClaw gateway manages webhook endpoints automatically -- the skill registers callbacks against the gateway's own webhook receiver, which routes results back to your connected messaging channel. No external endpoint configuration is required by the user.
Webhook events: job.completed, job.failed, batch.completed, quota.warning.
