    // --------------------------------------------------------------------------------------------------------
    // Note: The code for setting up the Chilkat REST object and making the initial connection can be done once.
    // Once connected, the REST object may be re-used for many REST API calls.
    // (It's a good idea to put the connection setup code in a separate function/subroutine.)
    // --------------------------------------------------------------------------------------------------------
