Answer 1

Hi Cindy,
you must set X-RequestDigest.

To get X-RequestDigest string call HTTP service (HTTP POST) with address <website-url>/_api/contextinfo and extract FormDigestValue from ResponseStatusCode.

Answer 2

One last question
will using SPD and REST call SP API and X-RequestDigest still work with 365? I do not know how long we will be on premise with SP 2019.
