I am working on a game for a client and he has some real gifts he'd like to send to players when they make some in-game purchases in virtual currency. For example, player earned some coins in game play and he enters the gifts shop, fills shipping info and makes e.g. "Gift card" purchase. Now my client wants some notification where he can get info about player name, his shipping details (stores as player data already), the purchased gift, etc...
Which strategy would you suggest me for such a scenario? I thought about making a Rule which fires when player specific inventory item added and then send email about that. Or maybe make a webhook to outside server? Or maybe run a cloud script, but don't have an idea yet what that script would do :)
Any ideas?
Thanks
