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

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

Dim jsonToken As Chilkat.JsonObject

' The access token JSON looks something like this:

' {
'   "expires_in": 3600,
'   "x_refresh_token_expires_in": 8726400,
'   "refresh_token": "L011546037639r ... 3vR2DrbOmg0Sdagw",
