I am trying to upload a bill with a memo to QBO. The bill is showing up correctly however the memo is not. I see in the files that the transaction's Memo property is hidden by it's child PurchaseByVendor Memo property, but not sure if this is the error or not.

What query would I use to retrieve all line items on all invoices?

Any chance entity classes could be marked as Partial so it's easier to write extensions for them? I don't know if you could somehow implement [NotMapped] (or similar) to prevent any custom properties from being sent to Quickbooks which would likely cause errors. I use this method with EF scaffolded entities and SQL Server.

I am trying to update the bill by using this code but looks like it doesn't work.

           ` var dataService = new DataService(token, long.Parse(realmId), useSandbox: true);
            var billResponse=( await dataService.QueryAsync<Bill>("SELECT * FROM Bill")).Response;
            if (billResponse != null)
            {
                var bill = billResponse.Entities.FirstOrDefault();
          
                // update bill here
                bill.PrivateNote = "sample memo";
                bill.Memo = "Memo";
                await dataService.PostAsync(bill);
            }`

Any idea?

It seems that the DataService is not able to void a payment.

var dataService = new QuickBooksSharp.DataService("AccessToken", "RealmId", useSandbox: true);

// https://developer.intuit.com/app/developer/qbo/docs/api/accounting/most-commonly-used/payment#void-a-payment
// Use a sparse update operation with include=void to void an existing Payment object;
// include a minimum of Payment.Id and Payment.SyncToken.
// The transaction remains active but all amounts and quantities are zeroed
// and the string, Voided, is injected into Payment.PrivateNote, prepended to existing text if present.
// If funds for the payment have been deposited, you must delete the associated deposit object before voiding the payment object.
var payment = new Payment()
{
    Id = paymentId,
    SyncToken = syncToken,
    status = EntityStatusEnum.Voided,
    sparse = true,
    PrivateNote = "Voided by QuickBooksSharp"
};

var result = await dataService.PostAsync(payment);

Any idea if we can actually do this?

Is there any way to delete items such as invoices with QuickBooksSharp?

Also, any plans to add additional properties to entities such as ProjectRef to Invoice?

(Thank you for your work by the way)

Hi, just wanted to see if this topic has been under your consideration @clement911 . It seems that QuickBooks is making some back-end change to their security flow on March 1st 2024.

Thank you

I do not seen a mechanism for refreshing the tokens (aside from instantiating a new DataService). There is also no way to update the tokens manually since the variables are private/protected and readonly.

This presents issues in an ASP.NET application where the DataService is injected, since there is no way to correctly re-instantiate an instance of IDataService.

Is the CodeGen generating the object that is received from the Webhooks Notifications?

Cannot seem to find the object that QBO is sending when hitting the Webhook. Is it included or generated by the XSD?

Is DataService thread-safe, or should each thread instantiate its own?
