Resource IDs are generated and returned in the responses, and later used in the workflow to complete the payment.
Step 2: Make an authorize call with the klarna, customer, and the basket resource that you created in step 1.
Step 3: Forward the customer to the redirectUrl that is displayed in the response.
Step 4: Once the customer makes the payment on Klarna hosted page, forward the customer to the returnURL of your shop as previously specified in the authorize call.
