How do I integrate my WooCommerce store with Klarna?

Head to your WooCommerce store dashboard, and choose the desired Woo Klarna plugins you want to install, activate, and configure:

Klarna payment solutions

Klarna Checkout (KCO) for WooCommerce, intended to replace the WooCommerce checkout
Klarna Payments (KP) for WooCommerce, enables Klarna payment methods within your WooCommerce checkout
The activated Woo Klarna plugin must match your chosen Klarna product (KCO vs KP) selected for your Klarna merchant contract, otherwise there will be API errors
Klarna Order management for WooCommerce (recommended, but not required)
Klarna On-site messaging

Additional documentation is available from the plugin developers and included in Krokedil documentation.

On-site messaging for WooCommerce

We offer On-site messaging for your WooCommerce store. To add Klarna On-site messaging, you’ll need to make some small changes and additions. Check the Support guide on installation steps for your WooCommerce store and FAQs.
