Unable to get variantId for free products

Questions
1

Hi,
I am trying to fetch the variant Id

var variantId = orderCarrier.OrderRows.FirstOrDefault(x => x.ID.ToString() == paymentRow.ReferenceID)?.ArticleNumber;

This works fine for all products, except when a free product is added from campaign,
and hence, I am not able to get the variant.

Kindly advice what needs to be done here ?

Litium version: 7

Can you expand a bit more on your scenario? When are you trying to fetch the variant id?

Hi @NilsN

here is some more code :

foreach (var paymentInfoCarrier in orderCarrier.PaymentInfo)
{
foreach (var paymentRow in paymentInfoCarrier.Rows)
{
switch (paymentRow.ReferenceType)
{
case Foundation.Modules.ECommerce.Payments.PaymentInfoRowType.OrderRow:
// here is where I need the variantID
// this is inside the litium.voyado plugin, need to fetch variant details.
}
}
}

issue is only when the product is free product.

I tried this locally, putting your code in a simple test controller with the following code and I get the expected variants. Is your product setup different? My free gift product is using the template Product with only one variant.

public IHttpActionResult Index()
{
	var orderCarrier = ModuleECommerce.Instance.Orders.GetOrder("LS100008", ModuleECommerce.Instance.AdminToken).GetAsCarrier(true, true, true, true, true, true);

	var variants = new List<string>();

	foreach (var paymentInfoCarrier in orderCarrier.PaymentInfo)
	{
		foreach (var paymentRow in paymentInfoCarrier.Rows)
		{
			switch (paymentRow.ReferenceType)
			{
				case Foundation.Modules.ECommerce.Payments.PaymentInfoRowType.OrderRow:
					// here is where I need the variantID
					// this is inside the litium.voyado plugin, need to fetch variant details.
					var variantId = orderCarrier.OrderRows.FirstOrDefault(x => x.ID.ToString() == paymentRow.ReferenceID)?.ArticleNumber;
					variants.Add(variantId);
					break;
			}
		}
	}

	return Json(variants);
}

The order LS100008:

Screenshot-OrderDetails821×388 12.4 KB

The response:
JSON-Response

This was tested using a standard Accelerator of Litium 7.2.3.

@NilsN
I am using the version 7.3.0
This is how my order row looks.

This is the final variantId’s that I get, null represents the free product.

So what could be possible wrong here.

If the order is re-calculated, then the added rows from campaigns will be removed and then added again, that make them get a new OrderRowID and the reference is not matching any more. Is the order re-calculated after it is placed?

Hi @patric.forsgard
I have checked this and the campaign row get a new OrderRowId even before the order is placed.
It keeps changing when we refresh the checkout page.
