Testing Klarna
This article provides further instructions on how to test Klarna plugin. To test Klarna, you need a special test account created by Klarna, apply for a test account early in the project to have it ready by the time you start to test.
When you are using the test account, change your configuration with isTestAccount attribute set to true in the Litium.Studio.AddOns.Klarna.dll.config file.
To create invoices and buy using test account, use test persons listed in Klarna API site:
https://developers.klarna.com/en/se+php/kpm/test-credentials
Multiple-accounts in same installation
If you have multiple Klarna accounts, give attention to the butik number combobox when searching for orders in Klarna. Selecting the wrong butik will result in Klarna stating that invoice is not found when searched.

Klarna campagins (Partpayment options)
Klarna campaigns are displayed in the "Visa butik" section under "Kampanjer". These campaigns are loaded only when Webserver is re-started.
