InvoiceXpressDotNet

InvoiceXpress API port to .net.

This implementation is based on the information at https://invoicexpress.com/api InvoiceXpress API from http://invoicexpress.com

The source code is almost totally generated with T4 Text Templates, to facilitate the generation of the data transfer objects.

The xml de/serialization is handled by XmlSerializer with some fiddling to make everything works.

How to use

First of all, you need a invoiceXpress account and a api key. From there you can get the following data needed to make the api calls

string _accountName = "your account name here";
string _apiKey = "your api key here";
string _accountId = "your accountId key here";

To use this api just call the nested static methods inside each module class, like so :

InvoiceXpress.Invoices

InvoiceXpress.Invoices.List(...);
InvoiceXpress.Invoices.Create(...);
InvoiceXpress.Invoices.Update(...);
...

InvoiceXpress.CreditNotes

InvoiceXpress.CreditNotes.List(...); 
InvoiceXpress.CreditNotes.Create(...); 
InvoiceXpress.CreditNotes.Update(...);
...

Examples

Invoices

Create and finalize a Invoice

var invoice = new InvoiceDto();
invoice.Date = DateTime.Today;
invoice.DueDate = DateTime.Today.AddMonths(1);

// Create/associate the customer
var client = new ClientDto();
client.Name = "Some Customer";
invoice.Client = client;
invoice.Observations = "Generated with InvoiceXpressDotNet";

// Create some items for the invoice
var item1 = new ItemDto();
item1.Name = "Some amazing product";
item1.UnitPrice = 100;
item1.Quantity = 1;
item1.Discount = 5.5F;

var item2 = new ItemDto();
item2.Name = "Some not so amazing product";
item2.UnitPrice = 0;
item2.Quantity = 1;

// add items to the invoice
invoice.Items = new ItemsDto { Items = new[] { item1, item2 } };

// create the invoice
InvoiceDto invoiceReturnData = InvoiceXpress.Invoices.Create(_apiKey, _accountName, invoice);

// consume the returned data
Console.WriteLine(invoiceReturnData);

// finalize the invoice
if (invoiceReturnData.Id.HasValue)
{
    var state = new InvoiceChangeStateDto { State = DocumentState.Finalized };
    var returnState = InvoiceXpress.Invoices.ChangeState(_apiKey, _accountName, invoiceReturnData.Id.Value, state);
    Console.WriteLine(returnState);
}

List Invoices

InvoicesDto invoices = InvoiceXpress.Invoices.List(_apiKey, _accountName);
foreach (InvoiceDto invoice in invoices.Items)
    Console.WriteLine(invoice.Id);

Get a Invoice

InvoiceDto invoice = InvoiceXpress.Invoices.Get(_apiKey, _accountName, invoiceId).Dump();
Console.WriteLine(invoice);

Get the invoice pdf

var pdfData = InvoiceXpress.Invoices.Pdf(_apiKey, _accountName, invoiceId);
// check if the pdf id ready to be downloaded, if not you will need to try again later
if (pdfData.IsPdfReady)
{
    string downloadTo = Path.Combine(Environment.GetFolderPath(System.Environment.SpecialFolder.Desktop), Guid.NewGuid() + ".pdf");
    using (var wc = new WebClient())
        wc.DownloadFile(pdfData.Pdfurl, downloadTo);
		
    //Process.Start(downloadTo);
}
else 
    Console.WriteLine("Document is not ready yet, try again later.");

Email a invoice to someone

var clientEmail = new EmailClientDto();
clientEmail.Email = "[email protected]";

var email = new EmailMessageDto();
email.Client = clientEmail;
email.Subject = "here is your invoice";
email.Body = "the invoice is attached to the message";

InvoiceXpress.Invoices.EmailInvoice(apiKey, accountName, invoiceId, email);

Invoice Receipt

Create and finalize a Invoice Receipt

pretty much the same as the Invoices.Create method

var invoiceReceipt = new InvoiceReceiptDto();
invoiceReceipt.Date = DateTime.Today;
invoiceReceipt.DueDate = DateTime.Today.AddMonths(1);

// Create/associate the customer
var client = new ClientDto();
client.Name = "Some Customer";
invoiceReceipt.Client = client;
invoiceReceipt.Observations = "Generated with InvoiceXpressDotNet";

// Create some items for the invoice
var product1 = new ItemDto();
product1.Name = "Some amazing product";
product1.UnitPrice = 200;
product1.Quantity = 1;
product1.Discount = 5.5F;

var gift = new ItemDto();
gift.Name = "Gift";
gift.UnitPrice = 0;
gift.Quantity = 1;

// add itens to the invoice
invoiceReceipt.Items = new ItemsDto { Items = new[] { product1, gift } };

// create the invoice
InvoiceReceiptDto createdInvoiceReceipt = InvoiceXpress.InvoiceReceipts.Create(_apiKey, _accountName, invoiceReceipt);
Console.WriteLine(createdInvoiceReceipt);

var stateChange = new InvoiceReceiptChangeStateDto { State = DocumentState.Finalized };
if (createdInvoiceReceipt.Id.HasValue)
{
    InvoiceReceiptChangeStateDto state = InvoiceXpress.InvoiceReceipts.ChangeState(_apiKey, _accountName, createdInvoiceReceipt.Id.Value, stateChange);
    Console.WriteLine(state)
}
