On-Site Messaging: Customizing Content

Certain supported content in the On-Site Messaging Platform can be customized to better suit the look and feel of the website it is displayed on.

Most common promotions support some level of customization, while content specific to the Klarna brand is more restrictive.

The look and feel of content can be set at the placement level through the On-Site Messaging App in the Merchant Portal . Changes made in the portal and published will be live immediately.

How to customize content and placements

Log into the Merchant Portal app

Navigate to the placements page and select the placement to customize by clicking the Custom Design button

Preview changes to make sure everything is correct

The customized content will be validated for contrast and readability. Hints will be displayed if a selection is not supported.

Once you are happy with the design changes, click Publish and Confirm. Your changes will be live immediately.

Setting a theme in the placement tag overrides any custom design content. Read more about themes .

You can reset to the default at any time.

You can only have one custom font css per MID and country. This can contain any number of fonts, only constrained by character count. Once added fonts will be available for all placements that support customization.

Check the preview and if everything looks correct, click “Confirm”. When updated and saved correctly a success message will appear. Click “OK” to close.

You can now use the added font-family from the font selector.

Frequently Asked Questions on Customization

I have published a new version, but when I visit the website I still see the old design.

Make sure you do not have a theme set that would override the custom content. Also, make sure to clear your browser cache. Browsers may cache the content for up to 24h.
