[Notice] API Update: OAuth 2.0 Authentication Flow Now Available

We are pleased to announce the release of the MSU OAuth 2.0 Guide, providing builders with a complete reference for implementing user authentication and token management in their applications.

▶ What's New

The following documentation has been added to the official API Docs:

• MSU OAuth 2.0 Guide — A step-by-step guide covering the full OAuth 2.0 Authorization Code Grant flow, including token issuance, refresh, introspection, and revocation.
• OAuth Endpoint Reference — Detailed specifications for all OAuth endpoints (/oauth/authorize, /oauth/token, /oauth/introspect, /oauth/revoke, /.well-known/jwks.json).

For detailed specifications, request and response examples, and integration guides, please refer to the updated MSU OpenAPI Docs.

▶ Who Needs This

Builders accessing Market endpoints that require user authentication must implement the MSU OAuth 2.0 flow to obtain a Bearer token in addition to their API key.

We encourage all builders to explore the latest API capabilities and implementation details through the updated documentation.

Thank you for your continued commitment to the MapleStory Universe ecosystem.
