Can I use Klarna express checkout button in my UK store?

Topic summary

Klarna cannot currently be used as a Shopify accelerated/express checkout (fast checkout buttons in cart/checkout) or as a supported Klarna Express Button within Shopify. There is no timeline or ETA; enabling this is up to Shopify, though Klarna states it’s a top priority and requests merchants keep sending feedback to Shopify.

Interim options:

  • Klarna On‑site Messaging app to display financing/payment info. As of 2022‑12‑15, Shopify Plus stores can place these messages within checkout. This is not equivalent to express checkout but is an improvement.
  • Some merchants have custom‑coded workarounds to mimic Klarna Express behavior, but these are not official integrations.

Pricing/commissions: Klarna takes standard payment processing fees when customers choose Klarna at checkout. Questions about affiliate‑style commissions (e.g., 17%) weren’t resolved; merchants were directed to Klarna Business Support for specifics.

Issues reported: A “Sorry, something went wrong” popup when attempting an express button in a minicart was redirected to another thread; an app install error (“failed request with status code 404”) was reported without an in‑thread fix.

Status: Unresolved and ongoing; key open question is when/if Shopify will allow Klarna Express Checkout.

Good morning @KristiAtKlarna ,

is it possible to integrate it now? Would be so important for our conversion rate!

Thanks in advance - looking forward to your answer.

Best regards and a happy Christmas time,
