    //  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:

    //    "location": "[BUCKET_LOCATION]",

    json.UpdateString("location","us");
    json.UpdateString("storageClass","multi_regional");

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

    //  curl -X POST --data-binary @[JSON_FILE_NAME].json \
    //       -H "Authorization: Bearer [OAUTH2_TOKEN]" \
    //       -H "Content-Type: application/json" \
