Hello Webflowers,
I am very happy to share with you that Stripe has released a Public Beta for Klarna which means that with some coding-skills (as far as I understand) Klarna can now, through stripe, be integrated and used for Webflow Ecommerce. I know this is on the wishlist and I have made plenty of requests myself.
