In principle, you should be able to simply rename the service URL in the FME Server admin interface, under Admin > Services.
Not working we get an ( http 404 not found)
Hi @boubcher,
this might be possible if, in addition to the service URL, you also change the folder name of the service accordingly in <FME_Server_Install_DIR>\\Utilities\\tomcat\\webapps.
Please note that this is not tested on our side, so proceed with caution as you might need to revert your changes if you experience any problems.
The solution I would recommend is to use a 3rd party application to create an API for your FME services. Here is an article demonstrating this with AWS API Gateway:

If you want to use a different cloud service provider, you could look into solutions such as Apigee Edge or 3scale. If you're looking for an on-premises solution, you can consider products such as Nginx API Gatewayor Kong.
Hope this helps!
