With today’s Steamworks SDK update, we’ve released The Steam Inventory Service beta, a new feature available to developers with games or software on Steam. The Steam Inventory Service is a set of new Steamworks APIs and tools that allow a game to enable persistent items that have been purchase or unlocked by individual users without having to run special servers to keep track of these user’s inventory.
With this service, a game can easily drop items to customers based on playtime or can grant items based on specific situations or actions within the game. These items can be marked as tradable through Steam or sellable via the Steam Marketplace. Developers can also configure recipes for crafting different combinations of items that result in more rare, unique, or valuable items.
This new service adds to the list of APIs available for free to Steamworks developers, including achievements, cloud saves, authentication services, error reporting, leaderboards, matchmaking, Steam Workshop, peer-to-peer networking, in-game overlay, downloadable content, and much more.
