  notes: >-
    The Adfin API uses OAuth 2.0. Platform-to-platform integrations use the
    client-credentials flow; biller authorization uses the authorization-code
    flow. App credentials (client_id + client_secret) are issued by an Adfin
    Integration Manager and presented as HTTP Basic auth against the API's own
    token endpoint (Basic base64(client_id:client_secret)). This is distinct
    from the Auth0-backed end-user identity at auth.adfin.com used by the
    console.
