SteamBuyGoodsRequest

Processes a 'orderid' from a Steam.

The GameSparks platform will validate the 'orderid' with Steam and process the response. The 'orderid' from the response will be recorded and the request will be rejected, if the 'orderid' has previously been processed, this prevents replay attacks.

Once verified, the players account will be credited with the Virtual Good, or Virtual Currency the purchase contains. The virtual good will be looked up by matching the 'itemid' in the response with the 'Steam Product ID' configured against the virtual good.
