    // 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

    // the service account access token was saved to a text file.  This example fetches the access token from the file..

    // ---- Step 1

    // Send a POST equivalent to this curl command

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