Settings used by Klarna

The Adobe Commerce Admin lets you configure and manage your store. Not all configuration options available in Admin impact Klarna.

Klarna uses the following key settings:

• Klarna payment method setup
• Catalog and cart price rule
• Currency
• Delivery methods
• Products
• Shop URL
• Taxes: rules, zones, rates, and calculation configurations

Once you’ve installed the extension from the Adobe Commerce marketplace, you need to set up some settings for Klarna in the Admin so that the payment method is usable.

The most important settings are related to the Klarna API. Apart from that, there are other settings to configure so that Klarna will operate smoothly in your store.

You can find Klarna's configuration in the Admin in Stores > Configuration > Sales > Payment Methods > Klarna:

With catalog and cart price rules you can allow your customers to buy products at reduced prices. You can find the price rules in Marketing > Promotions.

Since the rules have an impact on the price of a product and the shipping costs, it also affects creating orders with Klarna. Klarna takesthese rules into account and sends the adjusted prices through the API.

Using Klarna requires the correct currency setup. You can find the currency configuration options in Stores > Configuration > General > Currency Setup.

The selected Currency value will be sent through the Klarna API.

If the currency configuration is incorrect, Klarna API requests may fail. For example, if a customer places an order with the billing address in Germany, but the currency is the US Dollar, the request will fail. In this case, a currency mismatch error between the address and the currency is returned and the desired Klarna product can’t be used.

When a customer reaches the checkout, they can choose the desired delivery method for their order. You can configure this setting in Stores > Configuration > Sales > Delivery Methods.

The selected Delivery method can affect the total order value. Klarna takes this into account and this shipping cost information is sent to Klarna via the API integration.

To sell something in an online shop, products have to be configured. You can set up products in Catalog > Products.

Having the correct product configuration is critical as some information, for example, price, tax, and customer name, is passed to Klarna via the API during the Klarna order creation process. The details are later visible in the Klarna merchant portal.

The shop’s URL must be correctly configured so that the correct URL is used on all store pages. Klarna uses the base URL setting to ensure our products work correctly. For example, Klarna checkout needs a secure base URL for API callbacks and if the URL isn’t correct, Klarna checkout won’t work correctly.

You can set the base URL in Stores > Configuration > Web.

Tax settings are important to make sure you're following the tax rules of your country. You need to set them up in 3 places:

• To configure tax zones and tax rates, go to Stores > Tax Zones and Rates.
• To configure tax rules, go to Stores > Tax Rules.
• To configure tax calculations, go to Stores > Configuration > Sales > Tax.

Each of these settings plays a part when you're creating an order with Klarna. The tax calculation settings are especially important because they determine how taxes are applied and how prices for products and delivery are calculated.

Klarna takes these settings into account and sends the prices through the API.
