When to Load

Load this skill when the task involves Roblox Open Cloud REST APIs, API-key authentication, webhook setup, or HttpService calls to Open Cloud endpoints. Skip it for OAuth flows (use roblox-oauth), persistent data design (use roblox-data), gameplay networking (use roblox-networking), or pure engine API lookups (use roblox-studio-mcp).

Quick Reference

Open Cloud REST APIs

• Base: https://apis.roblox.com/cloud/v2/… (v1 for legacy)
• Auth: x-api-key: <API_KEY> header for server-to-server
• Content-Type: application/json for bodies
• Pagination: read nextPageToken, pass it back as pageToken query param
• Update masks: use updateMask query param for partial PATCH
• Long-running ops: poll the returned Operation resource with exponential backoff
• Error codes: INVALID_ARGUMENT (bad input), PERMISSION_DENIED/INSUFFICIENT_SCOPE (auth), RESOURCE_EXHAUSTED/429 (rate limit → backoff), UNAVAILABLE (transient → retry)

API Keys

• Use for: CI jobs, bots, web backends, in-experience automation (non-user)
• Each key has scoped permissions—confirm required scopes before coding
• Creator permissions AND key scopes must both allow the action
• Never store keys as plain text in experiences—use Secrets

Webhooks

• Requires public HTTPS POST endpoint
• Return 2XX within 5 seconds; process event async
• Verify roblox-signature header when secret is configured
• Deduplicate by NotificationId—deliveries may repeat
• Reject stale timestamps

HttpService Constraints (in-experience)

• Only certain Open Cloud endpoints are supported
• Allowed headers: x-api-key, Content-Type ONLY
• API key must come from a Secret (not plain string)
• HTTPS only; path params cannot contain ..
• Check endpoint support before coding

Handoffs

• OAuth / user consent → roblox-oauth
• Data schema / DataStore design → roblox-data
• Remotes / networking → roblox-networking
• Engine API lookup only → roblox-studio-mcp
