The following extensions may cause issues with Klarna:
- non-standard checkouts (e.g. one page checkouts) may not be compatible. While the extension code is built for compatbility whenever possible, it is only guaranteed and supported for compatibility with standard Adobe Commerce checkout.
- Amasty offers many extensions for Klarna, but some of them have incompatibilities. For example, in Amasty’s Store Pickup with Locator extension, where shipping fees are altered by Amasty code after the Klarna order is created rather than after the order has been invoiced, resulting in a Klarna capture that may not match the created Klarna order. To get help with this issue, contact Amasty support.
- Innoship may block payment methods. If Klarna isn't displaying in checkout, try deactivating Innoship to confirm if it's the root cause.
