How can I test my checkout?

To test your checkout you will need test Klarna API credentials. These can be found by signing up here with the same login details you use for the Merchant portal. It’s important to note that regular Klarna API credentials will not work with test mode in your Ecommerce. You can find more information about our Playground enviornment here
