C# 如何使用QBO rest api v3.0添加采购订单

我正在尝试发送使用Intuit.NET SDK v3创建的PurchaseOrder。我找到了一个发票的合适例子：

但我无法确定我需要做什么才能使其适用于采购订单。无论我设置什么属性，我都会收到错误请求

        DataService commonService = new DataService(context);

        QueryService<Vendor> accountQueryService = new QueryService<Vendor>(context);
        Vendor customer = accountQueryService.Where(x => x.Id == "9").FirstOrDefault<Vendor>();
        QueryService<Item> itemQueryService = new QueryService<Item>(context);
        Item item = itemQueryService.Where(x => x.Id == "1").FirstOrDefault<Item>();

        PurchaseOrder invoice = new PurchaseOrder();

        invoice.VendorRef = new ReferenceType()
        {
            name = customer.DisplayName,
            Value = customer.Id
        };

        /*invoice.APAccountRef = new ReferenceType()

        List<Line> lineList = new List<Line>();
        Line line = new Line();
        line.Description = "Description";
        line.Amount = new Decimal(100.00);
        line.AmountSpecified = true;

        //line.DetailType = LineDetailTypeEnum.DescriptionOnly;
        //line.DetailTypeSpecified = true;

        line.DetailType = LineDetailTypeEnum.PurchaseOrderItemLineDetail;

        };

invoice.Line=lineList.ToArray（）；

我试着在行中设置帐户并仅使用描述，但没有成功。如果我添加用上述代码创建的PurchaseOrder，我会收到BadRequest错误，其中包含验证异常

请有人给我指一下正确的方向好吗。我可能丢失了一些PurchaseOrder属性

我使用的是使用NuGet加载的August V3 SDK

不幸的是，我仍然收到错误的请求

更新2

经过更多的测试，我发现由于APAccountRef属性，它会给出错误。不设置此属性也可以

另一个问题是，我试图在行中使用PurchaseOrderItemLineDetail。不确定此类型是否正确（基于名称，它看起来像一个），但使用此详细信息类型会导致BadRequest错误。使用ItemBasedExpenseLineDetail是一种变通方法

我将设置玛纳斯的答案为正确，因为它给了我进一步调查的方向。但是非常感谢尼米莎·施里瓦斯塔瓦为h
