* 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..
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

loHttp = CreateObject('Chilkat.Http')
loHttp.AuthToken = loJsonToken.StringOf("access_token")

* Build a Google Calendar event:
loJson = CreateObject('Chilkat.JsonObject')
loJson.EmitCompact = 0
loJson.UpdateString("kind","calendar#event")
loJson.UpdateString("summary","Eat Lou Malnati's Pizza")
loJson.UpdateString("start.dateTime","2021-03-12T12:00:00-05:00")
loJson.UpdateString("end.dateTime","2021-03-12T13:00:00-05:00")

? loJson.Emit()

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

* {
*   "kind": "calendar#event",
*   "summary": "Eat Lou Malnati's Pizza",
*   "start": {
*     "dateTime": "2021-03-12T12:00:00-05:00"
