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

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:

If it was functional with the new Shopify 2.0 interface. I would have given 5 stars. I hope it comes soon! Until then we have to use something else that is easier to build with.

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. :)

Hello the updates were made on the wrong theme please check your email and get back to me.
Thank you

Changing themes inactivates the Klarna On-Site Messaging by design, as the code is not yet configured in the new theme, but you can easily go into the Klarna On-Site Messaging app and set the previously configured placement(s) to active, which I've done for your store just now. Please let us know if you need any further support.

The Klarna Onsite Messaging app has worked with the Minimal theme for other stores. We'd be happy to review your store to debug why the app isn't working. We see your support ticket generated from your email to skosm@klarna.com so we will continue to work with you via that support ticket.
