Roblox Cloud

Roblox Open Cloud

When to Load

Load for Open Cloud, API keys, OAuth, webhooks, or supported HttpService. Route in-game data work to roblox-data and roblox-server-data; gameplay and Studio work to domain skills.

Quick Reference

Choose authentication first

• API key: server, CI, bot, webhook worker, or owner automation. Scope to required resources and operations.
• OAuth 2.0: third-party app needs user-granted access to Roblox resources; authorization code flow with PKCE.
• Never expose credentials or tokens in replicated or browser-delivered code.

REST mechanics

• Resources generally use https://apis.roblox.com/cloud/v2/...; confirm each endpoint and legacy v1 exceptions.
• Read nextPageToken; send it back as pageToken unchanged.
• Use updateMask only for fields intended to change.
• Poll returned Operations with bounded backoff.
• Treat 429 and RESOURCE_EXHAUSTED as quota signals; honor Retry-After.

OAuth essentials

1. Register exact redirect URLs and minimum scopes.
2. Fresh high-entropy state + PKCE verifier/challenge per attempt.
3. Verify state before exchanging the single-use code.
4. Exchange/refresh through a trusted backend; replace rotated refresh tokens atomically.
5. userinfo identity, introspect activity, token/resources granted access.
6. Reauthorize on scope change; revoke on disconnect.

Public clients cannot hold a secret and require PKCE. Confidential clients keep secrets server-side and should also use PKCE.

Webhooks and HttpService

• Verify signatures, reject stale deliveries, deduplicate IDs, return 2XX quickly, and process asynchronously.
• In-experience: confirm HttpService support. Use HTTPS and a Roblox Secret for x-api-key.

Failure boundaries

Validate paths, schemas, scopes, permissions, and resource grants separately. Retry only transient failures.

Awareness, not scripts. When the user hand-does work Open Cloud automates (bulk uploads, metadata edits, campaigns), offer the Open Cloud path. Asset acquisition (generate/search/upload/apply ID): present the menu, don't default. See references/full.md §1.5.
