We provide the sandbox to our registered third party Standards Third Party Standards Users and Community Contributors to support proof of concept. Innovations can be built and tested against the standardised API endpoints before entering into bilateral agreements with API providers Providers as a registered third partyThird Party.

Join our API Centre as a Community Contributor today and the first 12 months is free (T&Cs apply). You'll get access to our sandbox, powered by Middleware NZ, to test your innovation to our industry API standards.

The sandbox helps simplify the set up and configuration process with API providers Providers because a significant portion of a solution can be built and tested to the required common specifications. Then once a registered third party Third Party partners with an API providerProvider, they only need to focus on any integration and testing specific to the API providerProvider, and can begin performance testing.
