    // 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 \
    //      -H "Authorization: Bearer [OAUTH2_TOKEN]" \
