We are managing all inventory items on characters, but the trading API doesn't support trading between characters. I was planning on transferring the items from character to player account before the trade, but this has to be done individually for each item. Is there a better solution for this if our trades can be up to 4 items for each player?
What is the time frame on any sort of trading API update? Will there be a better way to monitor incoming trades, or a way to trade between characters?
