description: >-
  The event surface of the Vodafone Business Messaging Hub. TPG Telecom documents
  outbound webhooks (callbacks) for inbound SMS, opt-outs and delivery reports, and
  runs a dedicated "Inbound System (Webhooks)" component on its status page — but
  publishes no AsyncAPI document, no event schema registry and no webhook signing
  scheme. Webhooks are configured in the console, not through an API, so there is no
  subscription endpoint to describe.

  surface: Messaging Hub console — Settings > API > Webhooks tab > New Webhook
