  Consumer Data Standards (DSB) CDR security profile + Bank of Sydney Open Banking
  page (https://www.banksyd.com.au/tools-support/open-banking/); the harvested CDS
  banking spec expresses scopes via the x-scopes extension rather than an OpenAPI
  securitySchemes block, so this profile is captured from the CDR regime it implements.
summary:
  types: [none, oauth2, openIdConnect, mutualTLS]
  public_surface: >-
    Product Reference Data (Get Products / Get Product Detail) is public and
    unauthenticated per the Consumer Data Standards - no API key or token required.
  authenticated_surface: >-
    All consumer account/transaction/payee/payment endpoints require CDR
    authorisation: an Accredited Data Recipient (ADR) acting under active consumer
    consent, using OAuth2 authorization-code + OpenID Connect hardened by the
    FAPI-based CDR security profile, with mutual-TLS holder-of-key sender-constrained
    tokens. No self-serve public developer credentials are issued outside the ADR
    ecosystem.
  oauth2_flows: [authorizationCode]

  - name: publicProductReferenceData
    type: none
    description: >-
      Public, unauthenticated Product Reference Data endpoints (listBankingProducts,
      getBankingProductDetail). No credential required; only the x-v version header.

    type: oauth2
    scheme: authorizationCode
    description: >-
      CDR authorisation via OAuth2 authorization-code flow. Authorization/token
      endpoints are published on the data holder's CDR authorization server (OIDC
      discovery), not on the resource host. Tokens are FAPI sender-constrained.

    description: >-
      OpenID Connect (CDR profile) for authenticating the consumer and issuing the

  - name: cdrMutualTLS
    type: mutualTLS
    description: >-
      Mutual-TLS (FAPI holder-of-key). Accredited Data Recipients present a client
      certificate; access tokens are bound to the presented certificate. The CDS
      spec servers[] advertise mtls.dh.example.com / tls.dh.example.com placeholder
      hosts for the MTLS and TLS variants.
