//  curl -X PUT https://example.com/v1/users/username \
//    -H "Authorization: Bearer your-auth-token" \
//    -d '{"password": "new-password"}'

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

//  {
//    "password": "new-password"
//  }

Chilkat.JsonObject json = new Chilkat.JsonObject();
json.UpdateString("password","new-password");

//  Adds the "Authorization: Bearer your-auth-token" header.
http.AuthToken = "your-auth-token";
