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.
Klarna Kosma XS2A API is one of 6 APIs that Klarna Kosma publishes on the APIs.io network.
Tagged areas include Open Banking, PSD2, XS2A, AIS, and PIS. The published artifact set on APIs.io includes API documentation and a getting-started guide.
