Klarna On‑Site Messaging

April 15, 2025

UPDATE: 10 days later I had a reply back although the person didn't know what the problem was. After highlighting that to them, someone else replied which didn't appear to know either but at least quoted Sara Nyrönen (Delivery Manager) in. Sara eventually replied and was very helpful. Essentially, we created a Klarna account ourselves before Shopify coming up with its own integration. Due to the integration, I believe that a second account was created automatically behind the scenes, but Klarna couldn't detect the correct one to use. Sara shared with us the correct Merchant ID which worked right away. Hopefully this will help somebody, both help desk and customers. PS. I don't know how it works now, 6 months later, but I believe the app should have at least a clear notification about this scenario and how to address it (e.g. raise a ticket with this specific request). INITIAL REVIEW Oct 2024: Now that Shopify integrates directly with Klarna, https://help.shopify.com/en/manual/payments/shopify-payments/local-payment-methods/klarna , this app shouldn't require a Klarna account to be able to enable the on-site messaging on the product page. Without an account this is useless. :( I have contacted merchant@klarna.com three days ago without an answer.

Doesn't work anymore,everytime open it just say"An error has occurred". No app block and be added in editor and even use the code snippets" " ,just flash the blurry klarna icon then gone? Update: A few weeks ago, they contacted us to manually install the code properly using the collaboration account. One star was taken away because of the late reply.

The app is good but with paypal it cause a conflict and paypal button is not showing in the cart. I know it cause a problem because i contacted shopify support and they said that klarna is causing this issue, can anyone help?

Great app. Although it has 1 (local) minor issue: the currency symbol is shown after the slided price, which isn't the default location for our currency (€). Is it possible to manually change this position? For example: Current on-site message: Betaal in 3 delen van 43,00 € Prefered on-site message: Betaal in 3 delen van € 43,00

Desperately trying to get this app to work. Been messaging support back and forth over email and going backwards with no clarity :( UPDATE: MARCH 2023 Dana from Klarna was in touch shortly after posting this review and has been amazing in going through and sorting out all issues with the app on store. I think there is unfortunately is a big difference between day to day level of support and higher level support. Klarna app now all operating smoothly as promised out of the box. Thank you Dana.

Its working pretty good. Only one big problem that i found is Ad blocker and tracking blocker. If my customer use Ad blocker then this app doesn't show at all on the website. That's why this apps is pretty much useless because now days all modern browser use Ad blocker. Can you please KLARNA fix that??

Unfortunately my experience in installing this app mirrors that of other reviewers. I had installed it but there was a glitch. Luckily the team responded very quickly and helped me sort it out immediately. It looks great!

Hello, I received this message about my Klarna integration. See below: "The following versions of these third-party payments integrations are not compatible with Shopify’s latest checkout. They will no longer be available after July 31, 2022: Buy now, pay later with Klarna." How can I can the update to the latest integration?

Slightly hard to integrate the app into the shop by myself and instructions unclear but support was very quick to respond and get the issue solved. Great responsive customer service.

This service will assist us in developing our business further and increase funnel as it provides multiple options of payment. In spite for customer service delayed reply; immediate support provided.

Ho usato ques'app per l'avviso agli utenti della possibilità del pagamento in rate, all'inizio ho avuto qualche difficoltà nel configurarla ma grazie al supporto rapido e gentile, son riuscito a configurarla nel migliore dei modi.

Great way to surface to customers that they can break up their payments—especially impactful for our store since our products are on the premium and pricey side. The UI was a little clunky to use, but I figured it out after some tinkering. There are good customization options built-in.

Onsite didn't work in the beginning but customer service was really fast and fixed it. Thank you! 5 star for customer service, but need to take one of from struggle in the beginning.

Placing the widget is always a little awkward but it gets the job done. The messaging that changes with order amount is nice on the cart page

Very good does exactly as described once installed correctly and support is very helpful so recommended.

Easy to install and use. A bit limited as to where you can place the ads. I am guessing because the app is new there will come more options eventually other than only the product page or cart. However, there is still a big problem with Klarna as a payment service when using Shopify: ONLY customer that are from the same country as the Shopify store can actually use the Klarna payments. It's because they have to be using the same currency as the store. So for example if someone from Norway tries to pay using Klarna in a Swedish Shopify store (that is using Swedish Krona as currency) they will not be able to complete the purchase, and instead get a message that "this payment option is not available" (without any further explanation why). This needs to be fixed. Therefore this application is just confusing customers from other countries because Klarna actually doesn't work for them... Otherwise the app itself was nice and I'm excited to see more features! 4/5.
