As Klarna Checkout transitions to Kustom Checkout, please note that parts of this documentation are still being updated. You may come across references to Klarna, outdated screenshots, or broken links.

We’re working continuously to revise all content, and we appreciate your patience during this process.

Notice: Kustom is switching their API endpoints.
If your store is still using the old endpoints, a warning may appear in the Kustom Merchant Portal.
The change will be fully enforced on March 31.
