Access to Custom Fields via API
I spoke with support, this is not supported at all. There is almost no point in setting up custom fields if we can't access them via the API when a new order is recieved at least. Is this in the works? if not, please vote to have this feature... its a big show stopper!

This is a very important issue and will only become more important as more order processing and fulfillment processes become automated. Please keep 1Shopping Cart up to date and competitive!
