# Look up Discord IDs by Roblox ID

> Returns Discord accounts linked to a Roblox user. Guild-scoped API keys must provide `guildId`; results are filtered to members in that guild. Set `resolved=true` only when you need expanded Discord profile data; resolved profile data requires a Premium API key.

    API v2 is the recommended Dock API for new integrations. It uses consistent
    response envelopes, stable error codes, request IDs, rate-limit metadata,
    and first-class bulk endpoints.


    Use the API only for legitimate verification, moderation, analytics, and
    automation workflows. Do not scrape, bypass rate limits, rotate keys or IPs
    to avoid limits, resell the service, or use detection outputs as definitive
    proof of wrongdoing. By using Dock, you agree to the Terms of Service and
    Privacy Policy.
