Files to exclude from optimization
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 You may come across references to Klarna, outdated screenshots, or broken links.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.
If you are using some kind of optimization feature there are files that needs to be excluded from any caching or concatenating.
