How does it work?

1. Customer opens your webshop, adds some items to the shopping basket, and clicks on 'Proceed to Checkout'.
2. Customer lands on your own checkout, and selects Klarna.
3. After creating a Klarna transaction using the create Klarna transaction endpoint, you redirect the customer to the provided URL.
4. The customer completes the payment, you receive a webhook (if you configured it for your Klarna transaction), and the customer is redirected to the Return URL(s) you specified on your Klarna transaction.
5. You make a request to the get Klarna transaction endpoint, and use its latest details to update your system.
