如何使用C＃和Quickbook SDK在QuickBook中添加发票？

Question

我是QuickBook（Desktop）集成的新手。 我想使用Quickbook SDK在QuickBook中创建发票。 我正在使用带有QuickBooks Desktop Edition的C＃.NET应用程序来创建客户和发票。

我可以创建客户，但无法开具发票。

这是我的代码：

ICustomerAdd customerAddRq = requestMsgSet.AppendCustomerAddRq();
customerAddRq.Name.SetValue(Customer.Name);

IMsgSetResponse responseMsgSet = sessionManager.DoRequests(requestMsgSet);
IResponse response = responseMsgSet.ResponseList.GetAt(0);
ICustomerRet customerRet = (ICustomerRet)response.Detail;

IInvoiceAdd invoiceAddRq = requestMsgSet.AppendInvoiceAddRq();
invoiceAddRq.CustomerRef.ListID.SetValue(customerRet.ListID.GetValue());

IMsgSetResponse invoiceResponseMsgSet = sessionManager.DoRequests(requestMsgSet);
IResponse invoiceResponse = invoiceResponseMsgSet.ResponseList.GetAt(0);
IInvoiceRet invoiceRet = (IInvoiceRet)invoiceResponse.Detail;

我得到的invoiceRet始终为null 。

另一个问题是IInvoiceAdd Invoice Number用户是哪个属性？

Answer 1

收到响应后，您将需要检查响应状态以查看请求是否有效。 例如：

IResponse invoiceResponse = invoiceResponseMsgSet.ResponseList.GetAt(0);
if(invoiceResponse.StatusCode !=0)
{
    // There was an error with the request.
    string errorMsg = invoiceResponse.StatusMessage;
}

在这种情况下，您将收到错误消息：“事务为空。” 这意味着您需要在发票中添加一些项目以在发票上创建美元金额。 即使OSR并未指出这些是必需的，即使它们的数量为零，您仍然需要将它们放在那儿。 就像您尝试在QuickBooks中手动创建发票而不指定任何项目一样。

假设您有一个名为“ Sales”的商品设置，那么您的请求将如下所示：

ICustomerAdd customerAddRq = requestMsgSet.AppendCustomerAddRq();
customerAddRq.Name.SetValue(Customer.Name);

IMsgSetResponse responseMsgSet = sessionManager.DoRequests(requestMsgSet);
IResponse response = responseMsgSet.ResponseList.GetAt(0);
ICustomerRet customerRet = (ICustomerRet)response.Detail;

IInvoiceAdd invoiceAddRq = requestMsgSet.AppendInvoiceAddRq();
invoiceAddRq.CustomerRef.ListID.SetValue(customerRet.ListID.GetValue());

// Add these lines to your request
IORInvoiceLineAdd invoiceLineAdd = invoiceAddRq.ORInvoiceLineAddList.Append();
invoiceLineAdd.InvoiceLineAdd.ItemRef.FullName.SetValue("Sales");

IMsgSetResponse invoiceResponseMsgSet = sessionManager.DoRequests(requestMsgSet);
IResponse invoiceResponse = invoiceResponseMsgSet.ResponseList.GetAt(0);
IInvoiceRet invoiceRet = (IInvoiceRet)invoiceResponse.Detail;

发票编号的字段称为RefNumber。
