I have requirement in APIMS where every product is associated with a network ID and rather than allowing the User to fill the network Id via the developer portal, the system should be able to identify the networkId based on the context product ( which is known when User selects the subscription key) and pass it as a Template parameter in the request to the backend service
So the get endpoint has something like /api/{networkId}/network/junctions
and the Template parameter networkId gets prepopulated with the networkId associated with the product
