Klarna Kosma Auth API
The Auth API is the client-session companion to the XS2A API. Whenever the Open Banking flow requires consumer interaction (bank selection, strong customer authentication, multi-step form completion), the Auth API exposes session-scoped endpoints to obtain and submit the forms the consumer must fill out. It is the API surface behind the embeddable XS2A App / JavaScript SDK and is hosted at authapi.openbanking.klarna.com.
Klarna Kosma Auth API is one of 6 APIs that Klarna Kosma publishes on the APIs.io network.
Tagged areas include Open Banking, PSD2, Authentication, and Consumer Sessions. The published artifact set on APIs.io includes API documentation.
