About Klarna Payments

General information about Klarna Payments

Klarna offers three different payment methods within the new Klarna KP API via : Invoice and hire purchase (Pay Later & Pay over time) as well as Sofort + secured direct debit (Pay Now). Merchants pass on all the invoice data during the order to the service provider, who then takes over the complete billing and debtor management. That than takes over the complete billing and downstream debtor management. As merchant you get a payment guarantee; no matter what payment method the customer chooses. Thereby your customers get financial flexibility with Klarna, as they can choose themselves between invoice purchase and hire purchase. In the case of purchase by instalment merchants can also specify the instalment amounts and dates of repayment. Merchants can use the billing solution also for their B2B commerce.

Rate payment at the online shop motivates your customers to order high value baskets. This also increases your turnover. Klarna guarantees online consents in seconds for purchases by instalment during the order process. A PostIdent-process is not necessary. Klarna transfers the invoice amount to the merchant and bears the non-payment risk themselves. As merchant you benefit from rapidly available liquidity.

All three payment methods with restrictions of secured direct debit are available in the following countries with their respective domestic currency: Germany, Austria, Netherlands, Danmark, Sweden, Norway, Finland, United Kingdom, USA, Switzerland, Australia, Belgium, Spain, Italy, Ireland, Poland, Portugal, France und Canada.

Klarna uses widgets in order to show customers the possible payment methods. The available payment methods for selecting depend on the previously selected category (see Create Klarna Session, PayType). The widget integration is done with the AccessToken (see Create Klarna Session, AccessToken) and the Klarna JavaScript SDK. How to integrate and initialise the Klarna JavaScript SDK and how to load the widgets is described on Klarna webpage:

https://docs.klarna.com/klarna-payments/integrate-with-klarna-payments/step-2-check-out/21-display-the-klarna-widget/
