  title: AccelByte Gaming Services (AGS) Achievement Session API
  description: Representative OpenAPI description of the core AccelByte Gaming Services (AGS) REST surface. AGS is delivered as a set of independent microservices (IAM, Basic, Cloud Save, Statistics/Leaderboard, Matchmaking, Session, Platform/Commerce, Season Pass, Achievement, DSMC/Armada, Game Telemetry, and UGC), each mounted under its own path prefix on the environment base URL (for example https://demo.accelbyte.io). Almost every operation is scoped to a `namespace` path parameter and secured with an OAuth2 Bearer access token issued by IAM. This document models a representative slice of each service rather than the exhaustive per-service specs, which AccelByte publishes individually.
