The Steam purchase interface is designed to handle microtransactions in-game, not DLC entitlements (use the external UI to show the Steam store for those) Steam microtransactions are not defined by the server, but rather by the client. UE lets us define these microtransactions in two ways

1) Config Driven Config driven microtransactions can be datamined, and can possibily be tampered if your backend server does not have the proper protections in place to verify the transaction. Therefore it is only recommended for development/debug flows. To add a new static microtransaction to Steam, add the following in your game's Engine file [OnlineSubsystemSteam] +StaticMicrotransactions=(Id=32bitinteger, Amount=costofitem, Description=myMicroTransaction)

2) Server-driven
