Commonwealth Bank NameCheck API
Documented in CommBank's business API catalogue: NameCheck is a security tool that helps organisations and their customers avoid false billing scams and mistaken payments by checking payee account name/number combinations before a payment is made. REST-based with OAuth 2.0 security. The OpenAPI specification is not published as a public download (catalogue access is granted at CommBank's discretion behind developer registration), so no spec is wired here to avoid fabrication.
