// This example assumes the Chilkat API to have been previously unlocked.

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

// curl -X PATCH \
// -H "Authorization: Bearer "$(gcloud auth print-access-token) \

// The following JSON is sent in the request body.
