Hello I have a couple of questions regarding the tradeOffers event and changes in trade offer states. Is the tradeOffers event only emitted when receiving a new trade offer? Is there an event that is emitted when a trade offer changes state? Is the only way to detect changes in trade offer states to poll Steam API GetTradeOffers? What are the rate limits of Steam API GetTradeOffers, is it based on IP Address or Steam Account, or?Thank you for any support, really loving your libraries.
