IPP .NET SDK for QuickBooks v3.0 Create Invoice Error – Bad Request

I am having a hard time figuring out what exactly is going wrong here – I do not get alot of insight form the error Bad Request – here is my code:

OAuthRequestValidator oauthValidator = new OAuthRequestValidator(accessToken, accessTokenSecret, consumerKey, consumerSecret);
                ServiceContext context = new ServiceContext(appToken, companyID, IntuitServicesType.QBO, oauthValidator);

                DataService service = new DataService(context);
                Customer customer = new Customer();
                customer.GivenName = "Mary " + DateTime.Now.Second;
                customer.Title = "Ms.";
                customer.MiddleName = "Jayne";
                customer.FamilyName = "Cooper";
                customer.CompanyName = "Mary " + DateTime.Now.Second;
                Customer resultCustomer = service.Add(customer) as Customer;

                Invoice invoice = new Invoice();
                //Mandatory fields
                invoice.DocNumber = Guid.NewGuid().ToString("N").Substring(0, 10);
                invoice.TxnDate = DateTime.Today.Date;
                invoice.TxnDateSpecified = true;
                invoice.CustomerRef = new ReferenceType()
                     Value = resultCustomer.Id

                Line invLine = new Line();

                invLine.Amount = 10000;
                invLine.DetailType = LineDetailTypeEnum.SalesItemLineDetail;
                invLine.Description = "Test Product";

                invoice.Line = new Line[] { invLine };

               Invoice resutlInvoice = service.Add(invoice) as Invoice;

                var invId = resutlInvoice.Id;

Basically I am generating a new customer (which work fine) and then I am trying to create an invoice for them with a single item on it.

Looking at what XML the documentation states here:

The NuGet package is missing a few things, which I know cant be true – form the documentation:

<Invoice xmlns="http://schema.intuit.com/finance/v3">

The Line object I get from this SDK has no properties for SalesItemLineDetail or ItemRef on it.

Anyone have a working example of this?

Method 1

//Find Customer
QueryService<Customer> customerQueryService = new QueryService<Customer>(context);
Customer customer = customerQueryService.ExecuteIdsQuery("Select * From Customer StartPosition 1 MaxResults 1").FirstOrDefault<Customer>();

//Find Tax Code for Invoice - Searching for a tax code named 'StateSalesTax' in this example
QueryService<TaxCode> stateTaxCodeQueryService = new QueryService<TaxCode>(context);
TaxCode stateTaxCode = stateTaxCodeQueryService.ExecuteIdsQuery("Select * From TaxCode Where Name='StateSalesTax' StartPosition 1 MaxResults 1").FirstOrDefault<TaxCode>();

//Find Account - Accounts Receivable account required
QueryService<Account> accountQueryService = new QueryService<Account>(context);
Account account = accountQueryService.ExecuteIdsQuery("Select * From Account Where AccountType='Accounts Receivable' StartPosition 1 MaxResults 1").FirstOrDefault<Account>();

//Find Item
QueryService<Item> itemQueryService = new QueryService<Item>(context);

TaxLineDetail taxLineDetail = new TaxLineDetail();
//Assigning the fist Tax Rate in this Tax Code

taxLine.AnyIntuitObject = taxLineDetail;

invoice.TxnTaxDetail = txnTaxDetail;

//Customer (Client)

//Billing Address

    name = account.Name,
    Value = account.Id

Invoice invoiceAdded = dataService.Add<Invoice>(invoice);

Method 2

This is one of the areas where the .NET devkit differs from the Java one.

You have to set the AnyIntuitObject property to the SalesItemLineDetail and then set the DetailType property to LineDetailTypeEnum.SalesItemLineDetail".

There’s a few bits and pieces around the framework that appear like this.

Here’s a short sample, although based on the comments it is not using the latest SDK.

Line l = new Line()
    l.AnyIntuitObject = new SalesItemLineDetail()
        ItemElementName = ItemChoiceType.UnitPrice,
        AnyIntuitObject = amount,
    DetailType = LineDetailTypeEnum.SalesItemLineDetail,

Method 3

I had created an invoice using V3 Java devkit. It worked fine. PFB request XML.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Invoice xmlns="http://schema.intuit.com/finance/v3">
            <TaxCodeRef type="TaxCode" name="TAX">TAX</TaxCodeRef>
        <DefaultTaxCodeRef type="Customer" name="TAX">TAX</DefaultTaxCodeRef>
    <CustomerRef name="TestDataCustomer620d5Sample1">1289</CustomerRef>
    <ARAccountRef type="Account" name="Account Receivable">QB:37</ARAccountRef>

Java code
List<Line> invLine = new ArrayList<Line>();
Line line = new Line();
line.setAmount(new BigDecimal("10000"));

SalesItemLineDetail silDetails = new SalesItemLineDetail();
ReferenceType refTaxCode = new ReferenceType();





Please check if you find some similar objects in .net devkit. I’ll try the same using .net devkit(It is not setup yet). When it is done, I will post the code.
