    Engine Plugin
    This product contains a code plugin, complete with pre-built binaries and all its source code that integrates with Unreal Engine, which can be installed to an engine version of your choice then enabled on a per-project basis.

A SteamAPI Inventory Interface integration that will allow you to implement a fully working Steam Inventory only using blueprints with the fewest nodes possible in the easiest way. This plugin allows you to do anything that the SteamAPI Inventory Interface allows for using blueprints.

This plugin works perfectly with the other plugins created by me:


  • Get Steam Item Definitions.
  • Download user's Steam inventory.
  • Consuming/Exchanging user's Steam items.
  • Item Drops.
  • Granting promotional items.
  • Item stack manipulation within a user's Steam Inventory.
  • Item generation (For Developers only).
  • Steam item dynamic properties.
  • Steam item purchase (micro-transactions).
  • ...and much more!

More features to come with future updates!

Technical Details


This plugin is safe to use on the client unlike the WebAPI. This plugin will not function properly without a correctly setup Inventory Service that you do through your Steamworks account that is linked with your Steam AppID. You can test this plugin with limited functionality by using the Spacewar AppID (480). Please use the documentation and example content as guidance; however it may require some tweaking within Blueprints to work with your personal Steamworks AppID.


  • OnlineSubsystem
  • OnlineSubsystemUtils
  • OnlineSubsystemSteam

These should already come pre-installed with the engine and should be automatically enabled as soon as you enable the plugin within your project.
