# 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..
$jsonToken = New-Object Chilkat.JsonObject
$success = $jsonToken.LoadFile("qa_data/tokens/googleSheets.json")
if ($jsonToken.HasMember("access_token") -eq $false) {
    $("No access token found.")
    exit
}

$http = New-Object Chilkat.Http
$http.AuthToken = $jsonToken.StringOf("access_token")

# To append values to an existing spreadsheet, our HTTP request body will
# contain JSON in the format of a "ValueRange".  For example, the spreadsheet we'll be
# adding to in this example looks like this:

# 

# The JSON ValueRange for the cells in the above spreadsheet is:
# {
#   "range": "Sheet1!A1:B5",
#   "majorDimension": "ROWS",
#   "values": [
#     [
#       "Item",
#       "Cost"
#     ],
#     [
#       "Wheel",
#       "$20.50"
#     ],
#     [
#       "Door",
#       "$15"
#     ],
#     [
#       "Engine",
#       "$100"
#     ],
#     [
#       "Totals",
#       "$135.50"
#     ]
#   ]
# }

# This example will append 6 cells (3 rows / 2 columns).
# We'll be appending the following:
# 
# "Paint", "$100"
# "Brakes", "$100"
# "New Total", "$335.50"
# 

# The range of cells we'll be appending is A1:B5
# Therefore, the ValueRange JSON we'll be sending in our POST body is:

# {
#   "range": "Sheet1!A1:B5",
#   "majorDimension": "ROWS",
#   "values": [
#     [
#       "Paint",
#       "$100"
#     ],
#     [
#       "Brakes",
#       "$100"
#     ],
#     [
#       "New Total",
#       "$335.50"
#     ]
#   ]
# }
