If an order does not sync to Revel the club manager will receive an order notification with subject "WARNING: Revel API error on order sync " There will be a link "Click here to review orders."
The intention of this is to alert the club manager that an order did not push over to Revel, so it can be resolved before there is a potential issue with a member coming in to pickup, and the order not being there.
The most common cause of this is when a product doesn't exist on Revel or there's an API limit issue.
