*  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 Sheets scope.

*  In this example, Get Google Sheets OAuth2 Access Token, the access
*  token was saved to a JSON file.  This example fetches the access token from the file..
loJsonToken = CreateObject('Chilkat_9_5_0.JsonObject')
lnSuccess = loJsonToken.LoadFile("qa_data/tokens/googleSheets.json")
IF (loJsonToken.HasMember("access_token") = 0) THEN
    ? "No access token found."
    RELEASE loJsonToken
    CANCEL
ENDIF

loHttp = CreateObject('Chilkat_9_5_0.Http')
loHttp.AuthToken = loJsonToken.StringOf("access_token")

*  First get the cells in the range A1:B5
loHttp.SetUrlVar("range","Sheet1!A1:B5")
loHttp.SetUrlVar("spreadsheetId","1_SO2L-Y6nCayNpNppJLF0r9yHB2UnaCleGCKeE4O0SA")
lcJsonResponse = loHttp.QuickGetStr("https://sheets.googleapis.com/v4/spreadsheets/{$spreadsheetId}/values/{$range}")

*      [
*        "Totals",
*        "$135.50"
