notes: >-
  Kaleyra exposes an event/callback surface (not a published AsyncAPI document).
  Delivery reports (DLR), inbound messages, and status updates are pushed to
  customer endpoints via configurable Callback Profiles per channel; Kaleyra
  Video additionally offers programmable Webhooks with a 200-OK ack + retry
  logic. Callback authentication supports basic, advanced (HMAC), and payload
  encryption. This captures the webhook/event catalog; no AsyncAPI spec is
  fabricated.
