Is there a way to pass the OrderId in the download link?

The download link is attached to the product so I would imagine it would need some kind of token but are they available?

For example, http:///mydomains.com/downloadlink.aspx?orderid=[[OrderId]]&sku=123

Hi Kevin,

Thanks, no problem.  Our downloads are unique.  We build the download 'on the fly'.  We also limit the number of downloads and have an expiration on how long the download will be available. 

I think we can use the VariantID as an alternative.

The issue with that is that it isn't stored anywhere in the order?  How do you know what variants (tshirt color, size, etc) that are associated with the product in the order?  All it saves is the product sku.

thanks,
Craig
