ASB APIs

Designed to industry standards, our APIs let you offer secure payments and build smarter, faster, and more connected financial experiences your customers can trust.

Open banking APIs

These help you offer secure, seamless payment and data-sharing services to your customers—direct from their bank account. They’re built to Payments New Zealand API Centre standards and are designed to make life easier for you and your customers.

Whether you’re creating a budgeting application, payment solution, or something totally new—our APIs give you the tools to connect securely and responsibly.
