  note: >-
    None of the three anonymously downloadable Swagger 2.0 documents declares a
    securityDefinitions block, so this profile is searched from the operation parameters
    and the provider's own product documentation rather than derived mechanically. Tata
    Communications runs three separate authentication regimes across three separate
    developer properties; there is no single account, no single token, and no shared
    identity provider between them.
schemes:
- name: Akana Authorization header
  type: apiKey
  in: header
  parameter: Authorization
  where: developer.tatacommunications.com (Akana Community Manager)
  required: true
  spec_declared: false
  sources:
  - openapi/tata-communications-number-intelligence-api.json
  evidence: >-
    The Number Intelligence API declares a required header parameter named "Authorization"
    with the description "used for authentication in Akana". It is an operation parameter,
    not a securityDefinitions entry, so no scheme type, no token format, and no token
    endpoint are machine-readable.
- name: Akana application id header
  type: apiKey
  in: header
  parameter: appid
  where: developer.tatacommunications.com (Akana Community Manager)
  required: false
  spec_declared: false
  sources:
  - openapi/tata-communications-mobile-messaging-exchange-account-administration.json
  evidence: >-
    All three Mobile Messaging Exchange Account Administration operations carry an "appid"
    header parameter, which is the Akana Community Manager application identifier issued
    when an app is registered against an API contract.
- name: MOVE OAuth 2.0 bearer token
  type: oauth2
  flow: clientCredentials
  where: MOVE (Azure API Management, move-external-apim-prod)
  spec_declared: false
  token_api: https://move-external-apim-prod.developer.azure-api.net/api-details#api=tata-move-api-access-manager
  scopes_published: false
  evidence: >-
    The MOVE developer portal publishes a dedicated "Move Access Token API — API to generate
    Access Token (OAuth 2.0 bearer token) to access Move APIs" alongside the MOVE SIM Connect
    and MOVE IOT Connect APIs. The token API's own reference is behind portal sign-in, so the
    grant type, token endpoint URL, and any scope list are not anonymously verifiable; no
    RFC 8414 or OpenID Connect discovery document is served on the host.
- name: DIGO auth token (issued on request)
  type: apiKey
  in: header
  where: DIGO CPaaS (tatacommunicationsdigo.io)
  spec_declared: false
  self_serve: false
  evidence: >-
    "You will need auth token to access our APIs. Please fill in your details below and we
    will get in touch with you." Access to the DIGO CPaaS APIs is sales-led; there is no
    self-serve credential issuance and no published token endpoint.
gaps:
- No securityDefinitions/securitySchemes in any published specification.
- No OAuth scope reference is published for MOVE, so no scopes/ artifact is emitted.
- No mutual TLS, no OpenID Connect, and no CIBA surface is documented anywhere.
- No anonymous sign-up path on the first-party Akana portal; the MOVE portal exposes
  /signin and /signup but everything behind them is gated.
