Order items in a payment plugin

I am writing a payment plugin and wonder how I can get order items from within IPaymentMethod.ProcessPayment().

this.orderService.GetOrderByGuid(processPaymentRequest.OrderGuid) returns null as apparently the order isn't created until paid.

Thanks!

You have the CustomerId in the ProcessPaymentRequest so you can get them from the customer's cart. See how it's done in the PayPalDirect plugin:

var customer = _customerService.GetCustomerById(processPaymentRequest.CustomerId);
if (customer == null)
    throw new Exception("Customer cannot be loaded");

//get current shopping cart
var shoppingCart = customer.ShoppingCartItems
    .Where(shoppingCartItem => shoppingCartItem.ShoppingCartType == ShoppingCartType.ShoppingCart)
    .LimitPerStore(processPaymentRequest.StoreId).ToList();

//items
var items = GetItems(shoppingCart, customer, processPaymentRequest.StoreId, currency.CurrencyCode);

The GetItems function is defined in the plugin so you'd need to implement that in whatever way makes sense for you're doing.

Great, thank you.

I was looking at Authorize.NET plugin, which doesn't have shopping cart code. I assumed the other payment plugins are similarly lean.

The ShoppingCartItems property is not available in v4.40

For 4.40, you'd use this:

//Shopping Cart
var shoppingCart = (await _shoppingCartService
                    .GetShoppingCartAsync(await _workContext.GetCurrentCustomerAsync(), Core.Domain.Orders.ShoppingCartType.ShoppingCart, (await _storeContext.GetCurrentStoreAsync()).Id))
                    .ToList();

//Tax
var taxTotal = Math.Round((await _orderTotalCalculationService.GetTaxTotalAsync(shoppingCart, false)).taxTotal, 2);

//Shipping Total
var shippingTotal = Math.Round(await _orderTotalCalculationService.GetShoppingCartShippingTotalAsync(shoppingCart) ?? decimal.Zero, 2);

//Order Total
var orderTotal = Math.Round((await _orderTotalCalculationService.GetShoppingCartTotalAsync(shoppingCart, usePaymentMethodAdditionalFee: false)).shoppingCartTotal ?? decimal.Zero, 2);
