WSO2 API Manager v1.8.0

I have a simple use case of mapping path param from the API consumer to the backend API endpoint. I have done a lot of research but have not found out the specific answer on how to do that. As per my understanding, thr mapping of the path parameter can't be done without the use of uri-template. Now the problem is that the API Manager does not support uri-template from the API Publisher user interface and you have to use url-mapping instead. One blog from WSO2 developer says that you can then go to the individual synapse config and change that to uri-template manually. But what is happening in pratice is that the updates made to the synapde config somehow triggers the database update that would happen from the publisher UI otherwise and the end result is that it does not work. Can someone please provide the way forward on how the path param can be mapped? FYI - the query parameter mapping is working for me since that does not need uri-template and can be implemented using url-mapping itself.

APIM 1.8 support both uri-template and url-mapping.You can define your url-template(or if you want uri-mapping) under resource section. please see the synapse config where i have added url-template and a url-mapping

in publisher I added /json as url pattern for url-mapping and /json/{id} for uri-template
