  description: >-
    HTTP Basic authentication (RFC 7617). The API Key is the username and the
    API Token is the password; both, with the Account SID, come from the
    Exotel Dashboard -> Settings -> API Settings. Credentials may be passed as
    an `Authorization: Basic base64(<api_key>:<api_token>)` header (recommended
    for production) or embedded directly in the request URL as
    `https://<api_key>:<api_token>@<subdomain>/v1/Accounts/<account_sid>/...`.
    Region subdomains: api.exotel.com (Singapore, default) or api.in.exotel.com
    (Mumbai/India). The Account SID also appears in every endpoint path.

notes: >-
  The AgentStream WebSocket (wss://) surface does not use this API Basic auth:
  Exotel connects outbound to a developer-hosted endpoint, and any auth is
  whatever you enforce on your own wss:// endpoint (e.g. a token in the applet
  URL surfaced back as custom_parameters).
