Starting January 31st, 2024, the /payments/details API call is no longer required for Klarna transactions. However, you can continue using this step to check the final payment status. To ensure you are informed of the final payment status for all transactions, you also need to use webhooks to update your order management system.
Accept Klarna payments using our APIs, and build your own payment form to have full control over the look and feel of your checkout page.
With our API-only integration, you can accept Klarna payments using either:
- The Klarna widget: the shopper completes the payment in your checkout.
For more information about the Klarna widget, see the Klarna documentation. - Redirect to Klarna: the shopper is redirected to Klarna to complete the payment.
When making a Klarna payment:
- Provide information about the purchased items by specifying
lineItemsin your payment request. - Indicate in your payment request if you want to use the Klarna widget or redirect to Klarna.
- Capture the payment after the goods have been sent. This triggers the payment instructions to be sent to the shopper.
