* 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..
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJsonToken = CreateObject('Chilkat.JsonObject')
lnSuccess = loJsonToken.LoadFile("qa_data/tokens/googleCalendar.json")
IF (loJsonToken.HasMember("access_token") = 0) THEN
    ? "No access token found."
    RELEASE loJsonToken
    CANCEL
ENDIF

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')
loHttp.AuthToken = loJsonToken.StringOf("access_token")

* Build a Google Calendar event:
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')

loJson.UpdateString("kind","calendar#event")

? loJson.Emit()

* This is the event JSON we'll be sending the HTTP POST:
