Most JS frameworks conveniently encapsulate that for you, eg jQuery's $.ajax() when told to use JSONP creates a uniquely named callback which wraps the callback you give to it, and passes that wrapper's name. Once called it calls your callback, then cleans up.
Sorry, please ignore my previous comment. After re-reading the thread
just now I realised I got mixed up between a callback in the JSONP sense
and in the WebHook sense (at first I was thinking in the latter). As you
point out, in the JSONP sense this would not be a concern.
