About the Download

Klarna Checkout for WooCommerce is a plugin that extends WooCommerce, allowing you to take payments via Klarna.

  • Klarna Checkout is available in Austria, Denmark, Finland, Germany, The Netherlands, Norway, Sweden, United Kingdom and the United States.
  • You need an agreement with Klarna to be able to use this plugin.
  • WooCommerce 3.0 or newer is required.
  • PHP 5.6 or higher is required.
  • A SSL Certificate is required.

Required WooCommerce Settings

  • 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.
  • It is recommended to enable guest checkout  (Enable guest checkout setting inWooCommerce > Settings > Checkout). If you don’t allow guest checkout you must check both Automatically generate username from customer email and Automatically generate customer password in WooCommerce > Settings > Accounts setting page.
  • Make sure that you disable the Display returning customer login reminder on the “Checkout” page feature in WooCommerce > Settings > Account. When the customer clicks the Place order button in Klarnas iframe the purchase is completed and this plugin will then trigger the start of WooCommerce checkout process. No error handling of required form fields are available in this step.
  • 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.
