item_type in steam community market
This question is similar to the question here. But I do not want to use the link wikia page in it because it is not updated. I would like to create such a page that I can update on a regular basis automatically getting data from steam servers. There is no way afaik in the steam community market pages that lets us see the gem value for an item that we do not own. However for an item that we do own, we can see the gem value in the steam inventory. The request that is made to steam servers to fetch the gem value (aka goo value) for an item looks like this: http://steamcommunity.com/auction/ajaxgetgoovalueforitemtype/?appid=[the app id]&item_type=[some number I am unable to make sense of] Example link for: A witcher 3 trading card presumably. Replace 5 with 15 on the link above and it is for an emoticon or background presumably. I would like to know if anyone has any light to shed on this matter as to what the item_type could mean here and how it corresponds to the different steam community items such as trading cards (normal), trading cards (foil), backgrounds, emoticons, etc.
