Stripe automatically presents your customers payment method options by evaluating their currency, payment method restrictions, and other parameters. We recommend that you configure your payment methods from the Stripe Dashboard using the instructions in Accept a payment.
If you want to continue manually configuring the payment methods you present to your customers with Checkout, use this guide (for example, to accept payments in Subscription mode). Otherwise, migrate to the dashboard.
Klarna is a single use, immediate notification payment method that requires customers to authenticate their payment. Customers are redirected to a Klarna page, where they select among multiple payment options (immediate full payment, payment in installments, or deferred payment). When the customer accepts the terms, Klarna guarantees that the funds are available to the customer and transfers the funds to your Stripe account. The customer repays Klarna according to their selected payment option.
Before you start the integration, make sure your account is eligible for Klarna by navigating to your Payment methods settings.
