we are just testing Stimulsoft, so probably my question is really newbee like

In our reports we want to get the data from a backend via RestAPI. The response is JSON formatted data.
So I thought that the "JSON Data" source is the right one. But the endpoint URL can vary, e.g. in development the backend runs on localhost, in production on a "real" server.
We would like to use a parameter/variable instead of the fixed URL:
Is this possible, and if so how?
Thanks,
Christian
