We recommend that you test your payment gateway using both your payment gateway's test and production (live) environments. Once you have completed testing in the gateway's test environment, it is recommended that you perform a test in your live production environment with a real credit card or account. If there are any differences in the configuration of your testing and production accounts, testing in production ensures your production merchant account is set up properly and can successfully connect to the production environment.
To test payment processing, you can use the test card or test account information and testing scenarios provided by the gateway vendor on the vendor's documentation website. For your convenience, we provide the links to the corresponding gateway vendor documentation website in the "Testing your configuration" section in Zuora's Knowledge Center article for each gateway integration. Note that these links to the vendor's website are subject to change due to changes made by the vendor. If you find the link in the "Testing your configuration" section is broken, please send feedback to us by clicking the Feedback button.
