Testing the checkout

Once the April checkout has been fully integrated into your page, it’s important to test its functionality.

April will provide a set of test API keys beginning with sandbox_ to test the integration.

Plugins testing

Merchants using an April plugin integration can simply replace their normal API keys in their plugin settings with the sandbox_ keys and go to their checkout.

Direct integration testing

In the web interface, merchants who have integrated using the direct API integration can continue to load the checkout script from the production URL previously given in Step 2 of the checkout integration page. The checkout widget will communicate with the correct April environment based on the public key you provide.

REST calls made from the backend server will require the host to be updated to api.sandbox.au.meetapril.io. Be sure to use the test API keys.

Below is a guide to filling fields in a test instalments payments plan.

Access the Merchant dashboard to view your test payments, initiate a refund for a test payment, and test the Virtual Terminal functionality (using the same test card information above).


Remember to replace the sandbox_ API keys with the normal keys after completing testing.
