    Cloudflare Stream sends webhook notifications when videos finish
    processing and are ready to stream, or when a video enters an error
    state. Webhooks can also be configured for live streaming events.
    Configure a webhook URL in the Stream dashboard or via the API to
    receive these notifications.
