Update API documentation to show notifications actually DO support recurring orders.
Your API clearly states that it ONLY supports NEW orders and not recurring... However talking with support, this is not true.
Supposedly you system DOES send notifications on all future orders as well (like recurring) but the API documentation does not show this.
You're right, we really should clarify that new orders include recurring orders. The system regards recurring orders in the same fashion as new orders, which is why we had not differentiated previously.
