Get started with Klarna on Shopify

Klarna can be integrated for a Shopify merchant either as:

1. a local payment method, for available regions, within Shopify Payments, supported by Shopify
2. an alternative payment method, for any available Klarna region, supported by Klarna

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
2. Klarna On-site messaging (free, public app in the Shopify app store). Prerequisite: Prior to messaging Klarna on your storefront using the public Klarna On-site messaging app, Shopify merchants should first integrate Klarna within Shopify checkout. (The On-site messaging app for Shopify is not compatible with Klarna as a local payment method within Shopify Payments yet, but this is in progress to be supported soon.)
