How can I test the Klarna integration?

To test your integration, you’ll first need a Klarna playground environment. You can sign up for our playground environment on our Docs website. Click “Merchant Portal” in the upper right-hand corner, select your region, and select Playground in the “Select Environment” field. Then click “Sign up”.

Once you have a Klarna playground account, you’ll be able to follow the normal integration process for your platform. If you are on one of our partnered platforms, you can find interactive instructions in the Integration Guides tab of the playground Merchant Portal. If you do not see your platform there, check our Docs website for written instructions.

If your integration process requires you to manually enter your Klarna API test credentials, you can generate and manage them in the playground Merchant Portal under Settings > API Credentials.

You can find more information about how to use your playground environment here on our Docs website.


Good to know: You do not need to have a live account with Klarna to sign up for a playground environment. Playground environments are not available for every region. Test integrations for Shopify are limited to select retailers. If you are a Shopify retailer and would like to test the Klarna integration, please contact our Merchant Support team to determine your eligibility.
