Question

我从Xero API收到验证错误：

发票无效，无法修改

该消息太笼统，我们不知道为什么要得到它或如何解决它。

我尝试了不同的状态值：

但是我得到相同的响应：

Answer 1

您只能修改状态为“ DRAFT”或“ SUBMITTED”的发票，如果它具有任何其他状态，则无法对其进行修改，您必须将其删除并创建一个新发票。

我相信您可能正在尝试修改API不允许的“授权”发票。

https://developer.xero.com/documentation/api/invoices

编辑：您需要根据状态删除或作废发票。这是使用.NET API的c＃代码的摘录。如果发票为AUTHORIZED，则需要将其状态设置为VOIDED；如果是DRAFT或SUBMITTED，则将其状态设置为DELETED

        var invoice = new Invoice();
        var api = XeroApiHelper.CoreApi();
        try
        {
            invoice = api.Invoices.Find(invoiceno);
        }
        catch (Exception ex)
        {
            // Handle the exception
        }
        if (invoice.AmountPaid == null || (invoice.AmountPaid != null && invoice.AmountPaid == 0))
        {
            if (invoice.Status == InvoiceStatus.Voided || invoice.Status == InvoiceStatus.Deleted)
            {
                //Invoice is already deleted or voided
                return false;
            }
            invoice.Status = invoice.Status == InvoiceStatus.Authorised ? InvoiceStatus.Voided : InvoiceStatus.Deleted;
            try
            {
                api.Invoices.Update(new List<Invoice> { invoice });
            }
            catch (Exception ex)
            {
                throw ex;
            }
            return true;
        }
        // Invoice has a payment on it
        return false
