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

; This example uses a previously obtained access token having permission for the 
; Google Calendar scope.

; In this example, Get Google Calendar OAuth2 Access Token, the access
; token was saved to a JSON file.  This example fetches the access token from the file..

    ConsoleWrite("No access token found." & @CRLF)
    Exit
EndIf

; Let's get the primary calendar.  A calendar ID could have be used instead of "primary".
$oHttp.SetUrlVar("calendarId","primary")
$oSbResponse = ObjCreate("Chilkat.StringBuilder")
$bSuccess = $oHttp.QuickGetSb("https://www.googleapis.com/calendar/v3/calendars/{$calendarId}/events",$oSbResponse)
If ($bSuccess <> True) Then
    ConsoleWrite($oHttp.LastErrorText & @CRLF)
    Exit
EndIf

If ($oHttp.LastStatus <> 200) Then
    ; Note: If a 401 unauthorized response is received, it likely means that the OAuth2 access token needs
    ; to be refreshed or re-fetched.
    ConsoleWrite("Error response status: " & $oHttp.LastStatus & @CRLF)
