  https://developer.hometrack.com/api-authentication (OAuth 2.0 client
  credentials via Auth0) + the Auth0 tenant discovery documents in well-known/ +
  the security schemes declared across all six OpenAPI documents in openapi/ +
  live anonymous probes of api.hometrack.com.

    Three distinct credential mechanisms sit in front of Hometrack's APIs and
    they are not alternatives — they are layers from different eras of the
    platform. (1) OAuth 2.0 client credentials against Hometrack's Auth0 tenant
    is the documented, current way to authenticate; the bearer token is
    presented to api.hometrack.com. (2) Every harvested OpenAPI additionally
    declares Azure API Management subscription-key schemes
    (Ocp-Apim-Subscription-Key header / subscription-key query), which is the
    gateway product key. (3) Two older APIs carry their own bespoke token
    exchange in the contract itself: the Valuation API exchanges an API key for
    a five-minute token used as `Authorization: Token token="<guid>"`, and the
    Hometrack API Public exchanges an API key for a plain-text GUID passed as a
    {token} path segment on nearly every operation. No credential of any kind is
    self-service — the portal directs you to a sales contact form.

  note: >-
    grant_types_supported on the tenant lists many Auth0 grants; only
    client_credentials is documented for API access, because the audience
    https://api.hometrack.com is a machine-to-machine API, not an end-user login.

    Documented on the portal but NOT declared in any harvested OpenAPI — the
    APIM export emits only the gateway subscription-key schemes. This is a
    genuine spec/doc divergence worth reporting to Hometrack.

  note: >-
    POST /authentication/{apiKey} returns a temporary token "valid for 5
    minutes". The spec documents that the header is also accepted without the
    quotes and without the `token=` prefix.
- name: PublicApiPathToken
  type: apiKey

  parameter: token
  exchange_operation: openapi/hometrack-api-public-openapi.yml#AuthenticationApi_Post
  sources: [openapi/hometrack-api-public-openapi.yml]
  note: >-
    POST /api/authentication/{apiKey} returns a plain-text GUID token that is
    then passed as a URL path segment on the reporting, brands, licences,
    partners, pvrplugin and trial operations. Credentials in the path are
    logged by intermediaries — recorded as an observed design weakness, not a
    recommendation.
