' 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 
' scope "https://www.googleapis.com/auth/cloud-platform"

' In this example, Get Google Cloud Storage OAuth2 Access Token, 
' the service account access token was saved to a text file.  This example fetches the access token from the file..

' ---- Step 1
' Create a JSON that contains the following information, replacing [VALUES_IN_BRACKETS] with the appropriate values:

' ---- Step 2
' Send a POST equivalent to this curl command

' curl -X POST --data-binary @[JSON_FILE_NAME].json \
