​
Resolved data

Use resolved=true only when you need display-ready profiles.
GET /v2/discord?resolved=true can return Roblox username, display name, description, creation date, ban state, verified badge state, avatar URLs, badges, and groups.
Resolved data is slower than raw mapping data because Dock must hydrate external profile details. Cache responses where appropriate and avoid requesting resolved=true by default.

​
robloxId

​

Optional IP seed for authorized detection workflows. Raw IP addresses are not disclosed in customer responses.
​
guildId
string
Required for scoped keys. Results are filtered to members of that guild.
​

Detection outputs are probabilistic and are not definitive proof of identity or wrongdoing. Review context before taking moderation action.

​
Verification status

With API-key auth and a discordId, this endpoint returns JSON status. 
GET /v2/verifications/discord?discordId=123456789012345678&guildId=987654321098765432
Without API-key auth, the same route redirects the user into the public verification flow and preserves query parameters such as pid, sid, and redirect.
