Endpoint reference

API key scope: full vs enroll

• full (default) — behaves as described throughout this page. Subject to the admin / non-admin visibility rules.
• enroll — create-only. An enroll key may call only POST /api/keys. Every other management route (list/read/update/delete keys — including the ones it created — plus /api/hits/recent, /api/api-keys, the audit log, and any session-reachable route) returns 403 forbidden, and an enroll key cannot log in to the dashboard. is_admin: true together with scope: "enroll" is rejected at validation.

• It can confirm and retrieve any key whose external_id it guesses. A POST /api/keys that collides with an existing external_id returns that key’s trigger URL, memo, public_id and expiry ("reused": true, HTTP 200) — see Idempotent creation — regardless of which API key created it. mantis device derives external_ids deterministically as mantis:device:<os>:<normalized-name>:<slug>, so an attacker who knows your naming convention can guess a machine’s ids and read back that machine’s canary URLs, which is exactly what lets an intruder route around the tripwires. Each such claim is recorded in the audit log as key.claimed.
• It can supply destinations on creation, and Mantis fires the activation ping synchronously — so the key can make your instance POST to an attacker-chosen HTTP(S) endpoint (private, loopback and metadata addresses are rejected unless ALLOW_PRIVATE_WEBHOOKS=1) or, if SMTP_URL is set, send it mail.
