+# **createOrder**
+> \Swagger\Client\Model\Order createOrder($authorization_token, $body)
+
+Create a new order

Among the other order details in this request, you include a URL to the confirmation page for the customer.<br/>When the Order has been successfully placed at Klarna, you need to handle it either through the Merchant Portal or using [Klarna’s Order Management API](#order-management-api). Read more on **[Create a new order](https://docs.klarna.com/klarna-payments/integrate-with-klarna-payments/step-3-create-an-order/)**.
+
