summary:
  types:
  - apiKey
notes: >-
  Kaleyra authenticates every REST request with the `api-key` HTTP header
  carrying the API key generated in the kaleyra.io console (e.g. "Ac4XXXXX21f").
  The account SID (Security Identifier) is supplied as a path segment
  (/v2/{sid}/... or /v1/{sid}/...). There is no OAuth 2.0 flow on the core
  messaging/voice/verify surface; Kaleyra Video issues short-lived access
  tokens for room/participant sessions via its REST API.
