This article provides guidelines on installing Order management in your WooCommerce store.
You have the possibility to handle your Klarna orders directly from WooCommerce.
Use the Klarna Order management plugin to automatically update Klarna when your Klarna WooCommerce orders are updated. This keeps order data in sync between Klarna and your WooCommerce store admin.
Your Klarna orders can be captured (fully), canceled, or refunded (fully or partially).
