What is On-site messaging (OSM) and how do I activate it?

(OSM) is a tool to let your customers know that Klarna is available on your website. 

By letting your shoppers know about the different payment options available before they reach the checkout can influence the purchase decision. 

  • All retailers using Klarna Payments or one of our checkout solutions are able to use our manual HTML integration. Everything you’ll need can be found in the

    of the Klarna Merchant Portal.

  •  Instructions on how to integrate using HTML can be found


Good to know: We support payment messaging, top-strip promotions, footer promotions, banners, and information page messaging. You can place the message anywhere on your website and in multiple places.
