# Upcoming changes to Klarna integration requirements

## **Background**
[Klarna](https://docs.stripe.com/payments/klarna) is a redirect payment method, meaning that a buyer must redirect from your checkout to a Klarna hosted user interface in order to complete the purchase. Currently the Stripe integration for Klarna requires you to pass the customer billing country ([payment_method.billing_details.address.country](https://docs.stripe.com/api/payment_intents/create#create_payment_intent-payment_method_data-billing_details-address-country)) in the [Payment Intents API](https://docs.stripe.com/payments/klarna/accept-a-payment?web-or-mobile=web&payments-ui-type=direct-api) request. Klarna uses the provided customer billing country to restrict the buyer to the Klarna sign-in flow for that given country. This means that if you’ve specified that the buyer is from Germany, the buyer cannot change their billing country after redirecting to Klarna.
## **What’s changing**
Effective October 1, 2024, Klarna will no longer force the customer’s billing country saved on their Klarna account to match the customer’s billing country that you pass in the Payment Intents request.
## **Impact to your business**
It is unlikely that any code changes are required from you, and we expect you to be able to continue accepting Klarna payments as usual.
However, depending on your integration with Stripe, you may be relying on the customer billing country for additional business logic in your systems. Here are some examples:
* You may be restricting Klarna to certain customer countries and relying on the customer billing country to enforce that restriction.
* Since [Klarna pricing](https://stripe.com/pricing/local-payment-methods) varies by customer location, you may be using this field to reconcile the Klarna fees that Stripe charges you.
If you have any business logic that relies on the customer billing country, Stripe now returns the customer’s billing country to you in the Charge API response for a successful Klarna payment (via the payment_method_details.payer_details.address.country field).
We recommend you consult with your engineering team to ensure there is no downstream system impact and make any required changes before October 1, 2024.
