Yes, that is definitely possible, and I'd say it's a major reason for the REST API.

You just have to make sure that there is is no firewall or router blocking access over port 80 (or 443 if you're using SSL) between the two machines.

Thanks David.

Apologies as I am asking some basic questions. If I use my system to store FME workspaces, how do I use it to publish or make it available through REST API from another system on the same network ?

Thanks in advance.

Don't worry about asking questions, that's why we're here :-)

To get a feel for the REST API, I recommend that you look at the FME Server Playground, there are lots of documentation and examples to look at:

Feel free to come back and ask more questions.

There are a lot of ways you can create an FME workspace. I found out about them on https://10roar.com/, and the article helped me out a lot. It's actually way easier than it seems. You'll first need to go into the file, then click generate workspace. You can also create a dialog. There are particular fields for the location and format of both the data to be read and the data to be written. There is a key requirement, though. I'm talking about the structure of the source data. All format selection fields let you type to search formats. Hope this helped!
