note: |
  HSBC Australia exposes two auth models. (1) The public Product Reference
  Data endpoints (GET /banking/products and /banking/products/{productId})
  are UNAUTHENTICATED by CDR design - product data contains no consumer data.
  (2) The consumer data sharing surface (accounts, balances, transactions,
  payees) is gated by the CDR security profile, an OpenID Connect / OAuth2
  FAPI flow restricted to Accredited Data Recipients (ADRs). The FAPI details
  below are read live from the OpenID Connect discovery document.
