When to Load
Load this skill when the task centers on Roblox OAuth 2.0 delegated authorization for Open Cloud — app registration, authorization code flow with PKCE, token exchange/refresh/revocation, scope selection, or OAuth-specific error debugging. Skip it for API-key automation, in-experience scripting, or general Open Cloud endpoint work (use roblox-cloud instead).
Quick Reference
Flow Selection
- Auth Code + PKCE — required for public clients (browser/mobile), recommended for all.
- Confidential — backend holds
client_secret; never expose in frontend code. - Public — no secret; PKCE mandatory.
PKCE Essentials
- Generate
code_verifier(43–128 char random) +code_challenge(SHA-256, base64url). - Send
code_challenge+code_challenge_method=S256in authorize; sendcode_verifierin token exchange. - One verifier per authorization attempt.
Authorization URL
GET https://apis.roblox.com/oauth/v1/authorize Params: client_id, redirect_uri, scope, response_type=code, code_challenge, code_challenge_method=S256, state, optional nonce.
Token Exchange
POST /oauth/v1/token — application/x-www-form-urlencoded Params: grant_type=authorization_code, code, client_id, code_verifier (public) or client_secret (confidential).
Token Lifecycle
- Auth code — seconds, single-use; exchange immediately.
- Access token — ~15 min; use as Bearer.
- Refresh token — ~90 days; single-use per refresh. Replace stored token atomically after each refresh.
- Revoke:
POST /oauth/v1/token/revokeon disconnect.
Scope Selection
- Minimum scopes matching actual endpoint needs.
openid→ ID token;profileonly if profile claims needed.- Medium/high/critical risk = least-privilege review signal.
- Changing scopes requires reauthorization.
Validation Endpoints
GET /oauth/v1/userinfo— identity claims.POST /oauth/v1/token/introspect— token activity (not resource auth).POST /oauth/v1/token/resources— resource-level access.
Key Rules
- Verify
statebefore using returned code. - Refresh tokens: server-side only.
- PKCE even for confidential clients.
- Don't mix API keys and OAuth.
