' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' See Get QuickBooks OAuth2 Access Token 
' for sample code showing how to obtain a QuickBooks access token for desktop apps.

' This example assumes we previously obtained an OAuth2 access token for QuickBooks.
