Klarna Financing is a payment method provided by Klarna AB, a popular Swedish bank, to payers in Europe. Klarna Financing provides a flexible financing option to the payers when they purchase goods online.
Payers enter a long-term financing agreement when they purchase an item and pay in installments. Payers can choose to repay in six to thirty-six equal monthly installments including interest (if any), pay a minimum amount each month, or pay off the entire amount within a month.
Klarna Financing is supported in the Mastercard Payment Gateway. This page describes integration details specific to Klarna Financing. It is recommended that you read the integration guidelines for browser payments, before building the Klarna Financing integration.
