Get started with Klarna on Shopify

Klarna can be integrated in a Shopify store via multiple different integrations (although it is generally recommended to not duplicate Klarna integrations, but rather have Klarna active in checkout only using a single integration), such as:

• an alternative payment method, for any available Klarna region, supported by Klarna
• a local payment method, for available regions (currently Sweden, Germany, and Austria), within Shopify Payments, supported by Shopify
• other integrations, based on region, such as Mollie, Global-e, and others. Shopify documentation lists available payment options by region, e.g. https://www.shopify.com/payment-gateways/sweden, and each is supported by the integrator

To check which Klarna integration is active in your store, go to your shop admin -> Settings -> Payments to review your store's active payments methods.

You can also review the names of Klarna payment methods in your store's checkout. The translated list of Klarna supported payment methods is available here. If Klarna is listed multiple times in checkout (e.g. Pay now with Klarna, Pay later with Klarna, and Finance with Klarna), the integration is not supported directly via Klarna, but rather supported by the integrating partner.

For Klarna as an alternative payment method, Klarna has 2 apps available for Shopify merchants:

1. Klarna (free, unlisted public app, as Shopify doesn’t allow payments apps to be listed in the Shopify app store) supporting Klarna Payments which allows your customers to pay with Klarna in your store's checkout
2. Klarna On-site messaging (free, public app in the Shopify app store). Prerequisite: Prior to messaging Klarna on your storefront using the Klarna On-site messaging app, Shopify merchants should first integrate Klarna within the store's checkout.

If you don’t yet have Klarna API credentials for the direct, alternative payment method, you can sign up at http://klarna.com/business

Once you have received your Klarna API credentials, please follow these steps to activate Klarna in your Shopify store.
