I have a rest resource configured from Rest UI page (let's say /entity/user: POST); I would like to share the endpoint with others devs so they can call the API (create users for e.g.). Where to get the list of fields to put on request body? also their structure (value or target_id..)?
Do you know a contrib module like this one that did the job for D7? https://www.drupal.org/project/rest_api_doc
Is there any programmatic practical way to have that? an API call or a drush command?
