Creating product/Service in Quickbooks Online in an Invoice line item

Question

I'm trying to create the service/product type in the invoice line item. It returns an error saying bad request, is my ItemRef phrased correctly. My service/product is created in qbo already, its called Subscription Fee, it's the 3rd in the dropdown list.

line.AnyIntuitObject = new Intuit.Ipp.Data.SalesItemLineDetail()
                            {
                                ItemRef = new Intuit.Ipp.Data.ReferenceType()
                                {
                                    Value = "3",
                                    type = "Item",
                                    name = "Subscription Fee"
                                },
                                ItemElementName = Intuit.Ipp.Data.ItemChoiceType.UnitPrice,
                                AnyIntuitObject = (decimal)item.Rate, // Line item rate
                                Qty = (decimal)item.Quantity,
                                QtySpecified = true,
                                ServiceDate = DateTime.Now.Date,
                                ServiceDateSpecified = true,
                                TaxCodeRef = new Intuit.Ipp.Data.ReferenceType()
                                {
                                    Value = taxCode0ZR.Id,
                                    type = Enum.GetName(typeof(Intuit.Ipp.Data.objectNameEnumType), Intuit.Ipp.Data.objectNameEnumType.TaxRate),
                                    name = taxCode0ZR.Name
                                },
                            };

What am i creating wrongly please help.

You cannot create an Item within an invoice or rather any entity within an entity. QBO v3 does not supports creating entities on the fly. You first need to do a create Item. Get the Id of that Item and refer it in your Invoice.

Also, enable request/response log to get the details of the errors in log files- https://developer.intuit.com/docs/0025_quickbooksapi/0055_devkits/0150_ipp_.net_devkit_3.0/0002_configuration/override_configuration
