Show Klarna payment information on product pages
21st September 2026
Webshops using Klarna can now display Klarna On-site Messaging alongside product prices.
How it worked before
Displaying Klarna messaging depended on a manually installed Klarna library and additional site setup. The Klarna client identifier was not managed through the normal Webshop payment settings, making the feature more difficult to configure and maintain.
What has changed
You can now enter your Klarna client identifier in the Klarna section of your Webshop payment settings and enable the Klarna widget.
When configured, Klarna promotional payment messaging can appear with the visible price on eligible product pages.
Your client identifier is available from the Klarna Merchant Portal under Conversion boosters and On-site messaging. Klarna uses different identifiers for its production and playground environments, so make sure you enter the one for the environment used by your Webshop.
Why this is better
Klarna messaging can now be configured through a supported Webshop setting instead of relying on custom installation work. This makes the setup easier to manage and helps ensure your website uses Klarna’s current Web SDK.
