如何使用C#中的QBO接口v3对发票进行支付？

Question

如何使用C#中的QuickBooks Online API v3将付款核销到现有发票？

我已经尝试了以下代码：

    private void UpdateInvoice(Payment payment)
    {
        Invoice oldInvoice = cmbInvoices.SelectedItem as Invoice;
        if (oldInvoice == null) return;
        Invoice invoiceToUpdate = new Invoice();
        invoiceToUpdate.Id = oldInvoice.Id;
        invoiceToUpdate.SyncToken = oldInvoice.SyncToken;
        invoiceToUpdate.Deposit = payment.TotalAmt;
        invoiceToUpdate.DepositSpecified = true;
        invoiceToUpdate.sparse = true;
        invoiceToUpdate.sparseSpecified = true;
        invoiceToUpdate.PaymentType = PaymentTypeEnum.CreditCard;
        invoiceToUpdate.PaymentTypeSpecified = true;
        invoiceToUpdate.PaymentMethodRef = payment.PaymentMethodRef;
        invoiceToUpdate.PaymentRefNum = payment.PaymentRefNum;
        invoiceToUpdate.CustomerRef = oldInvoice.CustomerRef;
        QBO.DataService.Update(invoiceToUpdate);
    }

它会失败，并显示以下错误：

{"ValidationException was thrown."}

我显然遗漏了什么，或者我一定是做错了什么。错误消息是无用的，希望Intuit能将其清除。

我对Intuit为他们的QuickBooks Online API v3发布的糟糕的文档感到相当沮丧，希望他们能开始清理它，让它变得有用。另外，请同时删除那些死掉的404页。

任何帮助或指点都是很棒的。

您只需要创建一个payment对象并将其与发票相关联。它成功地为我的QBO v3设置工作。

您将在"LinkedTxn“区域中链接发票，因此在本例中，我的InvoiceId为1282。我的ProccessPayment是假的，因为我们正在手动处理付款和登录QBO。

Payment p = new Payment
{
               PaymentRefNum = "73453",
               PaymentTypeSpecified = true,
               PaymentType = PaymentTypeEnum.CreditCard,
               UnappliedAmt = 0,
               UnappliedAmtSpecified = true,
               TotalAmt = amount,
               TotalAmtSpecified = true,
               ProcessPayment = false,
               ProcessPaymentSpecified = true,
               TxnDateSpecified = true,
               TxnDate = charge.Created,
               CurrencyRef = new ReferenceType { name = "US Dollar", Value = "USD" },
               Line = new Line[] { new Line
               {
                              Amount = amount,
                              AmountSpecified = true,
                              DetailType = LineDetailTypeEnum.PaymentLineDetail,
                              DetailTypeSpecified = true,
                              LinkedTxn = new LinkedTxn[] { new LinkedTxn { TxnId = "1282", TxnType = "Invoice" } } }
               },
               CustomerRef = new ReferenceType { Value = "123" }
};

值得一试的是，这件事给我带来了同样的问题。最后，它不喜欢不指定行项目，即使指定了稀疏更新。我发现了sdk工程师的引用，他说只需接受最初保存的发票，修改并将其传递给api。最终至少解决了我的问题。
