Gaijin Application Platform Documentation

Gaijin Application Platform (GAP) provides the backend infrastructure game developers need to ship online features: authentication, player data, leaderboards, inventory, matchmaking, and build delivery – all integrated within the Gaijin ecosystem. Use the Dev Portal and Central to configure services, manage access, and deploy your builds.
