README

This repository is READ-ONLY. It is split automatically out of the goldene-zeiten/products monorepo, which is the single source of truth. Pull requests and commits made here are overwritten by the next split — please open them in the monorepo instead.

Klarna as a payment method for the Products shop system, via Klarna's Hosted Payment Page. At checkout the customer is redirected to Klarna to choose how to pay (pay now, pay later, pay in instalments), returned to the shop where the order is placed, and Klarna's status callback confirms the same session. It plugs into the shop's existing payment-method seam, so it appears alongside invoice, PayPal, Stripe and any other configured method.

This first release covers the pay flow (open session, redirect, place order, status callback). Refunds and cancellations from the backend are planned as a later phase.
