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.
