Klarna (new) - Buckaroo development portal

General

Introduction

Important: Klarna is Collecting. If you are looking for our processing solution, please look at KlarnaKP.

Klarna provides the option for customers to pay after delivery in one time. The concept includes a customer risk check before the financial risk is transferred to Klarna. By transferring the financial risk to Klarna the merchant is eliminating the order related financial risk. To start the collection process Klarna needs to be informed on dispatch.

Klarna supports both a PayLater flow and a Slice-It flow. Both requests have the same parameters, only the action is different.

For PayLater, use the action "Pay"

For Slice-It, use the action "PayInInstallments"

The Pay Later flow is available in the following country-currency combinations:

NL - EUR
DE - EUR
AT - EUR
GB - GBP
DK - DKK
SE - SEK
NO - NOK
FI - EUR

The Slice-It flow is available in the following country-currency combinations:

DE - EUR
AT - EUR
GB - GBP
DK - DKK
SE - SEK
NO - NOK
FI - EUR

Slice-It is not available in the Netherlands.
