Setting Up Klarna

To offer your customers the benefit of paying with Klarna, you must first sign up for a Klarna account and gain access to the Klarna Merchant Portal. Then, complete the Klarna configuration from the Admin of your Magento store.

Important: Klarna does not support currency switches to display multiple currencies in one website. Magento uses a base currency and tax configured at the website level (not store view) to avoid rounding and mismatch issues. To support multiple currencies, create a website per currency, using different URLs configured at the Magento website level (not store view).
