No native support for adding Klarna as an IRL merchant. Only possible with a url workaround with a specific currency.
''......there are some limitations with Shopify when adding Klarna for multiple countries. Since Klarna requires to process relevant soft credit checks in order to enable the products, we can only process these with the original currency you settle your transactions with Shopify - meaning that, assuming you have GBP as your settlement currency, we can only offer Klarna UK for this particular URL. Basically it means that, if you are willing to have Klarna for multiple countries, based on your Shopify, you will require to have multiple URLs for different markets.''
What are other merchants using in place of Klarna in regions like IRL that are not supported?
Other payment instalment app recommendations welcome.
