- Make sure that you have enabled pretty permalinks in your WordPress installation. Otherwise callbacks from Klarna back to your store won’t work and orders will not be updated with the correct order status/information.
- To get the order total to match between WooCommerce and Klarna you need to configure WooCommerce to display prices with 2 decimals. More information about displaying of prices and how it can cause rounding issues can be found in this article.

Note that you need an agreement with Klarna for each country enabled and your store needs to be able to process purchases in the local currency.

With the iframe settings section you have the possibility to alter the appearance of the Klarna Payments Widget displayed in the checkout. Here you can change things like background colors, button colors and text colors.
Compatibility with themes & plugins ↑ Back to top
- Klarna Payments should work with most themes. However, the plugin is only tested with the Storefront theme and we do not guarantee that it will work with other themes. Common situations when errors occur are:
– Themes/plugins with customized template files for WooCommerce checkout page.
– Themes/plugins that removes standard checkout fields.
– Themes/plugins that modifies the checkout into a multi step checkout.
- The plugin and Klarna only handle product quantity that is specified as an integer. For instance you can’t send 1.5 as the product quantity to Klarna. If you sell products where you charge by length or dimension we recommend that you use the Measurement Price Calculator plugin.
Troubleshooting ↑ Back to top
- If Klarna Payments isn’t displayed as an available payment method in checkout page make sure customer billing country is one of countries you have entered Klarna Payments credentials for and that selected currency matches customer billing country.
