If you have received an SMS request to confirm your verification code on behalf of customer service, please reach out to Klarna immediately via the app. Verification codes should never be shared.

How do I integrate Klarna?

If you’re an administrator user in the Merchant portal, you’ll find platform-specific guides in the Products section. And you can always find more technical information on our Developers site or by contacting our Merchant support.

Integration testing

To test your integration, you’ll need Klarna API test credentials for our playground environment and test mode activated in your Klarna plug-in.

Once you request and get access to your test account, the next step is to log in to the playground/test version of the Merchant portal. There you’ll find your Klarna API test credentials by going to Settings > Klarna API Credentials.

 

Ok, I want to know more about the test environment.
