Guys...it’s 2020 why do I feel like I’m trying to build a gaming computer from scratch?? I, like many others have stated will just stick with quadpay and their flawless installation.

We're sorry you found the app too complex. We are continually working to improve the app. Also, support for the app is always available via skosm@klarna.com

Was really looking forward to having Klarna available on the site, but the app is buggy and not particularly user friendly. Needs some development, they're missing a trick here.

We're very sorry you are not happy with the app, and we'd like to try and improve any bugs and anything you didn't find user friendly. Please share specific feedback with us at skosm@klarna.com and we'll try to make it better!


Some of the instructions are kind of iffy and finicky and the customer service takes quite a few days to get back to you. But once you're communicating they do everything perfectly. I'm glad my website had them. :)

This doesn't seem to work. I don't understand how I cant show people how much they can pay. It seems like im not the only one having a problem.

Very frustrating app. It certainly doesn't do what it says on the tin. There seems to me to be so many bugs that need sorting out before this app is any good. I initially couldn't get it to work. The placements were not appearing on the pages I had assigned them too. i.e Product Pages, Cart, Home page etc.. Then all of a sudden they appeared. For some reason I had two product page ads active so I deleted one. That made all other Klarna placement ads dissapear from my site and it hasnt't worked since. It's a nice concept but it does not work with Shopify. Not yet anway. Come on Klarna sort this out. After all it is in your interests if you are wanting Shopify customers. Dissapointing.

Update: I have emailed and received no response. My store is not a development store. It's a real live store.

I can see how its really useful and i like it for the most part. I just can't seem to figure out how to replace my placement tags. So because of that i cant use this app.

Developer reply

Thank you for the review! Sorry to hear you've had a little difficulty replacing the placements tags. If you're looking to update / customise the placements, you'll need to log into the Klarna merchant portal. These are dependent on the Shopify theme you're using. You can find more information including the App Support Guide and an installation video here: https://www.klarna.com/international/business/shopify-on-site-messaging/

Alternatively you email skosm@klarna.com and our Support team will be able to talk you through the process. We hope this helps!

To concur with other reviews, I found it painful to set up and ultimately nothing happened, so deleted. Amazed that a company of Klarna's resources can't create a simple app that integrates with the world's largest ecommerce provider. Poor.
