Depending on which version of Episerver Commerce you're using you can use the IOrderRepository to get what you need. Here's a good example: OrderApiController.

Hope this helps.

Thank you Frederik. This OrderAPI controller is a built-in or custom ?

I need to get the order details when i'm checking out to payment. So how can I use the IOrderRepository to get the details like Order Id,customer Id, customer Name, Tracking number etc., . Can you please elaborate the process. I'm new to using Epicommerce.

Episerver provides a good reference site that I recommend checking out: Quicksilver. To load the order details you can use the IOrderRepository.Load() method, example:

_orderRepository.Load<IPurchaseOrder>(orderNumber);

Hope this helps.

Thank you Frederik. But I am referring QuickSilver demo project only. Upto my knowledge, as I want to send the order details to my service when the user checkouts, I should need the customer details also. But in that particular controller I'm unable to get the ordernumber using IOrderRepository. I mean I dont know the ordernumber so how can I load the order using this 

_orderRepository.Load<IPurchaseOrder>(orderNumber);

In that controller, what do you have if you don't have the order number?
