Klarna’s support is not responding me for 5 days, may be somebody else will be more lucky.
I already have test credentials for Checkout API version 2, and I need credentials forCheckout API version 3.

Details:

• What is the difference between the versions 2 and 3 of Klarna Checkout API?
• How to get test credentials for the version 3 of Klarna Checkout API?
