To test the flow, you first need to enable "Allow Test transactions" in QuickPay:


You also need enable Test Mode in the Centra-plugin. This is the only way to get test-payments approved.

You will need to disable test-mode for the plugin in Centra when you run it in production.

You can then use the test-cards provided by QuickPay to place test orders.
