Nakama API

The Nakama API is the core REST and WebSocket API for Heroic Labs' open-source game backend server. It provides endpoints for user authentication (social, device, email, and custom), account management, multiplayer matchmaking, real-time gameplay via WebSocket, leaderboards, tournaments, group and friend management, in-app notifications, storage, and remote procedure calls (RPC). The gRPC interface mirrors the HTTP API and is suited for server-to-server integrations. Client SDKs are available for Unity, Unreal Engine, Godot, JavaScript, Dart, Java, Swift, C++, and Defold.
