Klarna Docs - Known Constraints

Known Constraints

The following incompatibilities have been debugged and have been determined to not be compatible with the app:

These either block the preview of the storefront page within the app or block the storefront functionality of the app.

This app relies on Shopify standard use of certain theme variables, such as the product and template variables.  If theme code overwrites these variables in a non-standard manner, the theme will not be compatible, which has been encountered with the Shella theme by MPIThemes, although this incompatibility is in progress to hopefully become compatible soon.

e.g. if a liquid file contains:

{%- assign product = null -%}
{%- assign template = template.name | handle -%}

As Klarna Payments can only accept orders in the store’s base currency (which is a Shopify restriction for alternative payment methods per Known Issues), the on-site messaging is hidden when the selected currency does not match the store’s base currency when using standard currency switcher functionality.

Currently, for active Ad Positions, the app displays on-site messaging for all in-stock products.  

Currently merchants integrated with Klarna as a local payment method within Shopify Payments do not have access to the Klarna Merchant Portal and access to their Klarna API credentials, which are currently required for Klarna On-site messaging, but this is on our roadmap to support in the future hopefully.   This app supports stores with Klarna Payments integrated as an Alternative Payment Provider (under Shopify admin -> Settings -> Payment providers -> Alternative payments).

Any Klarna merchant can use static Klarna marketing images are available at "Marketing Assets" at docs.klarna.com

Unfortunately, not at this time.

The on-site messaging works on the storefront for these browsers, but the app configuration does not currently work on iPads (Safari) within the Shopify store admin. We recommend Chrome for the app configuration setup within the Shopify store admin.  We will review to see if this could be supported in the future.

App block support is coming very soon! More info about OS 2.0 at https://help.shopify.com/en/manual/online-store/themes/managing-themes/versions
