When processing Klarna transactions, keep the following in mind:
- Klarna does not support direct sale transactions (authorisations and data capture in one go). For each order, Klarna estimates a delivery date and issues a due invoice at the agreed date. Capture the transaction after you have sent the goods to your customers.
- Klarna allows you to perform partial and full refunds and to cancel authorisation.
Process flows
- Your customers finalise an order in your shop and select Klarna.
- You send this CreateHostedCheckout to our platform.
- You redirect your customers via the redirectUrl to the Klarna portal. They select their preferred payment method and confirm the order with their credentials.
- We receive the transaction result.
- We redirect your customer to your returnUrl.
- You request the transaction result from our platform via GetHostedCheckout or receive the result via webhooks.
- If the transaction was successful, you can deliver the goods / services.
Testing
Refer to our Test cases for test data and detailed instructions.
Make sure to use the right endpoint and switch back to the live URL as soon as you have finished your tests.

}- Mind that Billie shares the same paymentProductId=3302 with Pay Later/Pay Later (Pay in 3).
- If any of the Billie-specific properties are missing or incorrect, our platform will process your request as a standard Pay Later/Pay Later (Pay in 3) transaction.
Testing
- To perform test transactions, you need to have an agreement with Klarna to use Billie.
- Use the JSON sample in the "Integration with Billie" chapter to perform tests.
Make sure to use the right endpoint and switch back to the live URL as soon as you have finished your tests.
