User

The User subsystem provides access to Steam user identity data, including basic profile information, persona state, and avatar images.

This subsystem allows querying both local user information and limited data about other Steam users, making it suitable for player identity display, profile panels, and social UI elements.

Capabilities

  • Retrieve identity information for a Steam user by user ID.
  • Download Steam avatar images in different sizes.
  • Access the local user's Steam ID.
  • Retrieve the local user's persona name and persona state.
  • Retrieve the full identity struct for the local user.
  • Validate Steam user IDs.
  • Check whether a Steam user ID belongs to the local user.

Important Notes

  • User identity and avatar data is available only for friends or users known to Steam.
  • Avatar availability depends on user privacy settings and Steam client state.
  • Identity data is provided by Steam and may change dynamically as persona state updates.
  • The subsystem does not perform user authentication or account management.
