The `http request` node (and many others) can be configured with a blank url -- then, if the incoming `msg` contains a `url` field, it will be used in the http request. A good example of how to do it is in [this thread](https://discourse.nodered.org/t/injecting-messages-on-a-specific-node-for-building-approval-workflows/32640/12)

So I would suggest that your subflow includes a `change` node upstream of the http request node, which builds the target string and a sets it on the `msg.url` field. The only thing I'm not sure about is how to get the current subflow's id inside a `change` node... but if that's not available, just use another env var, maybe?
