This is an accepted solution.
Apologies, what I meant to say is that there is currently no way to distinguish the source of update.
To clarify, there is currently no way to see if the response is "order creation" or "order update", correct?
I suppose, since I happen to need to use XML instead of JSON for my stuff, I can different the TYPE of data ( order vs product vs inventory level ) by looking at the root node. I suppose I could also do the same thing in JSON, come to think of it. Just don't see how to tell the difference between "order creation" and "order update" responses. Is there?
From your answer above and the documentation, I am currently assuming we need a different URL for each event. Just being paranoid and confirming. Thanks.
