          Testing with us

          How do I access your test environment?

          You’ll find all you need to know about accessing our test environment on our Open Banking Implementation Guide.

            How do I register to use your test environment?

            Just like our production environment, we only support dynamic app registration through our APIs. You’ll need to hold valid OBIE certification in order to register your app with our test environment.

              What will I be able to test?

              You’ll be able to test all of the API endpoints that are available in our production environment, with the exception of the customer authentication flow, which has been amended for testing purposes. You’ll also be able to query our static test data and invoke all error responses.​

                Can I see dynamic changes to the test data?

                No, our test data is static. For example, any payments made from a test account will not affect the account balance.

                  Do you have any limits on how often or when I can use the test environment?

                  We won’t limit your usage time or the number of API calls to the test environment and we do our best to ensure it’s available around the clock. We’ll let you know in advance about any planned maintenance via the support section. To make sure we can provide a stable and reliable test environment for all of our users, we ask that you use the test environment for integration testing only.


                    How do I get in touch with you if I have a query?
