' 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 New Chilkat.JsonObject
Dim success As Boolean = jsonToken.LoadFile("qa_data/tokens/qb-access-token.json")
If (success <> True) Then
    Debug.WriteLine("Failed to load qb-access-token.json")
    Exit Sub
End If


' The access token JSON looks something like this:

' {
'   "expires_in": 3600,
'   "x_refresh_token_expires_in": 8726400,
'   "refresh_token": "L011546037639r ... 3vR2DrbOmg0Sdagw",
'   "access_token": "eyJlbmMiOiJBMTI4Q0 ... oETJEMbeggg",
'   "token_type": "bearer"
' }
