Install Klarna Shipping Services (KSS)

Getting started

1. Install Litium Accelerator 7.4.2 or 6.3.9.
2. Remove Klarna.Rest.Core reference from your projects if there is any.
3. Install or update the latest Klarna add-on.
4. Go to the Configure KSS section for configuration of the KSS.
5. Click here to make the site visible to Klarna background calls.

Add KSS to fresh Accelerator 

Follow the steps below to add KSS to the Accelerator checkout page.

1. Download the corresponding zip package.
   Litium Accelerator 7.4.2
   Litium Accelerator 6.3.9
2. Unzip and copy files to your Accelerator.
   These files are structured based on the Accelerator. If you want to see what are changed, you can use a file comparison tool to compare them.
3. Open solution, include new files and build.
4. Run BuildClientProjects.bat to apply the client changes.

Note - if you are combining KSS with other payment options and delivery methods you need to ensure that the flag IsCustomDeliveryCost is set to false on the delivery carrier if the delivery method is not KSS. This is in order to get the correct cost when calculating the order.

How it works

This sequence diagram describes both Accelerator and Klarna KSS integration.

1. When shoppers input their address or select a shipping method in the iframe, an event will be triggered to send the shipping option data to update into Cart.
2. At the same time, there is a request from the Klarna server to the Accelerator to update the Order on disc.
