Klarna Get Payment Authorization

Overview

Get Payment Authorization is the API call of Klarna's two-step checkout flow following Klarna JavaScript Initialization. The request is sent with the PaymentId and AuthenticationResult(redirectResult) appended in the return url to which the shopper gets returned(redirected) after the shopper finishes initial authentication process.

The same PaymentId must be used in the Get Payment Authorization request.

In Get Payment Authorization reply, ResponseCode is used to determine if the payment was successfully processed for that order. The order can be accepted when ResponseCode is APPROVED and must be rejected if the value is DECLINED.
