Cuscal

Cuscal Limited is Australia's largest independent provider of payments and regulated data services outside the Big Four banks, founded in 1966 and listed on the ASX (ticker CCL). An Authorised Deposit-taking Institution regulated by APRA and ASIC, Cuscal supplies the connectivity and processing layer beneath hundreds of banks, mutuals, credit unions, fintechs, non-bank lenders and corporates - carrying scheme card issuing and acquiring, the New Payments Platform (NPP) with PayID and PayTo, Direct Entry, BPAY, RTGS, ATM services, AI-driven fraud monitoring, and Consumer Data Right (open banking) data-holder and accredited-data-recipient services. Its acquisitions of Indue and the Paymark/Strategic Payments Services businesses broadened its issuer-processor and acquiring reach. Cuscal's API posture is B2B and relationship-gated: it runs a public-facing Developer Hub (ReadMe-hosted) documenting CMS REST APIs for card issuing, card controls and PIN services with webhook notifications, but the full reference and any machine-readable OpenAPI definitions sit behind client onboarding rather than open self-serve signup.

Cuscal publishes 3 APIs on the APIs.io network. Tagged areas include Payments, Australia, Card Issuing, Issuer Processor, and Real-Time Payments.

The Cuscal catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Cuscal’s developer surface includes documentation, developer portal, engineering blog, support, and 12 more developer resources.
