title: how to add invoice or sales receipt quickbooks rest api v3.0
body: <p>How can I add an invoice or sales receipt using the QuickBooks API Rest v3? Preferably in .NET. I was interested previously in v2 but apparently that is going to be replaced soon. I can't seem to find any sample code in .NET to add a sales receipt or invoice for version 3. A simple example with minimum data supplied would be appreciated.</p>
