Commonwealth Bank Fast Payment (Credit Transfer Initiation) API
Documented in CommBank's business API catalogue as the Credit Transfer Initiation / Fast Payment API: a near real-time capability that lets a business send money to most Australian financial institutions through the New Payments Platform (NPP). REST-based with OAuth 2.0 security. The full OpenAPI specification is not published as a public download — access to the catalogue and specs is granted at CommBank's discretion behind developer registration (partner-gated), so no spec is wired here to avoid fabrication.
