Klarna lets merchants add Klarna payment options to online, in-app and in-store checkout. Integrations are available through APIs, ecommerce platforms and payment partners; the payment options shown vary by market and customer eligibility.
Merchants can manage orders through the merchant portal or order management API. Compare the integration route, supported countries and currencies, fees and settlement terms; installment or deferred payment is not available for every purchase.
