Klarna Kosma

Klarna Kosma XS2A API

The XS2A API is the server-side endpoint set used by TPPs and merchants to create and control Open Banking sessions and flows under PSD2. The XS2A API drives Account Information Services (AIS) for retrieving accounts, balances, and transactions, and Payment Initiation Services (PIS) for initiating account-to-account bank transfers. Sessions are created against api.openbanking.klarna.com (production) or api.openbanking.playground.klarna.com (sandbox), and the resulting token is handed to the XS2A App for the consumer-facing strong customer authentication (SCA) flow.
