This seems like an obvious question, I have a published workspace with a user parameter on FME server 2019. I would like my user to be able to access a url where they could enter the paramater P=1234 (a data attribute search). I am not sure if I can do so without 2020. Unfortunately we are limited by our organization managing FME server for us and they haven't upgraded yet.
I assume there is no possible way in 2019, but I am throwing the question out there.
