Why does sysparm not work for me

[John Wallis]

I think anything involving the use of "sysparm_" does not work on POSTMAN!

This works in the SNow 'REST API Explorer' area.
sysparm_fields=sys_updated_on%2Csys_id

But: when I use the same string, same format, it doesn't work in the real situation.

[I went to the my dev ... area, and did a "REST API Explorer" query and the ... creates a wonderful query for me and appears to work within that environment.

Note: "limit" alone works, but "sysparm_limit" does not work.

My goal is to use something like this [original issue]
sysparm_query:sys_updated_on>javascript:gs.dateGenerate('2020-02-14','00:00:00')
and maybe the limit the fields 

confused 😕

All good John, unfortunately it's not always as easy as it should be

Hi John, I think the issue is more that normal\standard functionality is not working for you in the instance you are testing in, and to confirm this you should start by running your queries against a standard vanilla OOB development instance (and API) and not your companies dev box\custom API, as this may have customization's which are preventing the results you are expecting.
- You may also want to edit your response and remove the instance names from your example URLs.

Does V2 suggest anything here?
