Monthly financing- This is a credit option wherein Klarna partners with other financial institutions to give your customers flexible financing for larger purchases.

Troubleshooting Common Klarna Issues for WooCommerce

Setting Up Klarna Payments For Your WooCommerce Store

If you’re having trouble setting up your shop with Klarna Payments, fear not! There are some simple tips you can use to troubleshoot any common issues.

1. Storefront theme and third-party plugin issues

First, the Klarna Payments plugin is tested with all the WooCommerce Storefront themes. Problems may occur when you install third-party themes. So, make sure that your theme is tested for Klarna Payments.

Common error situations can occur if any of the installed plugins or themes-

-remove or alter standard checkout fields in WooCommerce.

-modify the checkout into a multi-step checkout.

-introduce customizable template files for WooCommerce checkout.

If this is the case, you may have to resolve either through customer support for the third-party plugins.

2. Product quantity

Another issue is with the product quantity. Klarna can only handle a product quantity specified as an integer. For instance, it’ll not accept product quantity as 1.5 or 2.5.

3. Currency convertors

The next issue is about currency conversions. WooCommerce doesn’t offer multi-currency support. You have to install plugins for it. Klarna Payments is only compatible with the Currency Switcher for WooCommerce plugin. So ensure that Klarna Payments works well if you install any other multi-currency plugin.

4. Account settings

If certain features seem to be missing or won’t work properly, it could mean that the settings in your account are incorrect. Double-check all of the settings and make sure that they are correct according to Klarna’s requirements.

5. URL whitelisting

You should also check if your shop’s URL is whitelisted in Klarna’s system. You will need to add your shop’s exact URL to the whitelist in order for it to work properly. If there are any typos in the URL, it may not work correctly so double-check everything before proceeding.

If these solutions don't help, try reaching out to their customer support for further assistance!
