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!

I am a new customer of Klarna, I have done the whole account process at Klarna in which it was approved. So far so good, but after installing the shopify application I received a notice inside the application that does not support the Online Store 2.0, how so? all the themes of shopify today are in this new version and you have no support? seriously that? what a technology delay... And now how do I install and use klarna? I sent a message to support yesterday and have not been answered yet either... They have already started badly in several aspects to be a company would be. I hope they help me and that they improve this outdated and confusing system of yours. Translated with www.DeepL.com/Translator (free version)

We'll certainly support you via your existing support case; please know that our support team will reply as soon as they can, but that may be a few business days depending on the case load.

This app does support Online Store 2.0 though, as documented at: https://docs.klarna.com/platform-solutions/shopify/on-site-messaging-app-for-shopify/install-steps/#add-placements-online-store-20-app-blocks

Hopefully you can share the details of the notice via the case emails so that we can clarify that, and provide any other support needed.

Da migliorare, sono riuscito ad attivare il servizio solo grazie all'assistenza, molto rapida e preparata. Non è intuitivo e fluido il processo

I had some initial difficulties in making the installments visible in the product sheets. Klarna's support intervened immediately and resolved the problem quickly. Now everything works fine.

App is not working. Klarna is the worst company you can ever find, nothing is working and the support is really useless.

Appears to be working fine - no coding input required and the integration was seemless. Not sure what so many people are having trouble with looking at some other reviews!

Thank you WorldRaceCircuits for this great review! We're very glad the app works well for you.

We've worked hard to improve the app over time, with a major update relating to Shopify's improved theme architecture for Online Store version 2.0, which enables our app to integrate better with themes using App Blocks, and avoids many of the issues merchants had previously.

Thank you again for taking the time to share a review; we appreciate you very much!

Why not possible when Using Klarna with Mollie? The mollie support its only working with Klarna direct? Please let us know if there is any chance on using that Plugin with Mollie?

Developer reply

July 13, 2022

Hi Haushaltsparadies,
This app can work for stores using Klarna via a Mollie integration, and others. As long as you have your Klarna merchant id, you can connect that merchant id in the Settings of the app.

If you need support, our team is happy to help, available at skosm@klarna.com

The registration was very easy. However, there is no tutorial of how and where the Javascript code needs to go within Shopify Website Code. I read some documents but still not able to get the Klarna On-Site Messaging to show I have Klarna payments integrated. The only way I know I have this is right at checkout, which is the last step. Other than that, customers will not know about Klarna payment option.

Hi Clifton Furnishings,
I see you have our On-site messaging app installed on your store, but no placements configured for product pages currently, e.g. https://cliftonfurnishings.co.uk/collections/bed-frame-1/products/westminster-bed-frame-in-elite-chenille?consoleDebug=true

Here is a link about how to add placements:

Our merchant support team would be happy to help you set those up if you email skosm@klarna.com

Here is a public demo store that does have a placement configured for a reference:
