Is anyone sending the RTD files to a Volusion shopping cart? If so, how do you handle multiple ProductCodes? I am having trouble with this. I have 5 unique products that can be designed in RTD. I have set up external notification to Volusion, but I can only find a way to pass a single ProductCode. I need a way to pass 5 unique ProductCodes and the ability to add more later. Anyone have any ideas?
