Klarna Docs - What you can test

What you can test

Ready for a smoooth testing experience?

In the test (playground) environment, you can test the integration of the following products in your online store:

  • Klarna payments lets you offer Klarna as a payment method to your customers.
  • Klarna checkout lets you offer Klarna’s checkout module in your online store.

Before you start testing the Klarna products, consider the following:

  • Our live (production) systems don't process the purchases completed in the playground environment. These test purchases won't result in invoices or fees.
  • Don’t use real personal data during testing. Depending on which country your store operates in, we offer sample customer data and sample payment data that you can use.
  • In the playground environment, you can test all Klarna products. The products you see in production may differ from the ones available in the playground environment, depending on your contract.

See what Klarna products look like when added to your store’s checkout or payment process.

When testing your store's integration with Klarna, you can:

Additionally, On-site messaging and Express button each have a testing solution that lets you apply Klarna's branded elements to your playground store. See the product documentation for On-site messaging and Express button to learn more about how to test them before going live.

We recommend that you perform some end-to-end tests before you launch. Take a look at the step-by-step test cases.

If you integrate using third-party platforms, see the platform integrations documentation.

To experience what buying with Klarna is like for your customers, go to our Demo store. The demo store is an example website that shows what the shopping journey can look like to the customers and how Klarna payments, Klarna checkout, On-site messaging, and Express button work.

The data in the Demo store is not linked to your MID. The orders you create using Klarna APIs or in the plaground Merchant portal are not visible in the Demo store.
