API Developer Portal

Welcome to the ASB Application Programming Interface (API) Developer Portal. ASB provides open and secure APIs to help developers create exciting solutions that meet customer needs.

ASB is currently working to provide APIs to support the New Zealand Open Banking standards. To find out more about Open Banking and to register your interest please visit Payments NZ and the API Centre. Registered users can use the Open Banking API Sandbox provided by the API Centre to build and test Open Banking APIs before engaging with ASB.

We are currently working on a new version of our developer portal so check back here regularly as we add more information to support partnering with ASB.
