I have been looking at the Api on wiki, but I'm not seeing how I can register for a purchase from a guild store vendor. If possible, I'm looking for a way to track a guild store purchases item details. Does anyone have any idea ?
Are you looking to hook into the event?
EVENT_TRADING_HOUSE_CONFIRM_ITEM_PURCHASE (integer eventCode, integer pendingPurchaseIndex)
Has the items index value. You should be able to respond to that?
It does look like that will be part of the solution. I guess next issue to solve is how to get to the actual item details from the item purchase index.. I guess I'll have to trial and error this.
