While a session is open, every other public API request from that browser sign-in is served as the person, except a request from the admin app, which is served as the staff member. The Management API always serves the staff member. Until changes while impersonating are released, every change except ending the impersonation is refused with `CH.003.153`. Once they are, a change is made as the person and its audit event names the staff member too, but a change to sign-in, access or a user's account (grants, roles, members, groups, users and their email and profile, invitations, teams, operation assignees, scheme shares, bridges, security settings, SSO and the organisation itself) is still refused with `CH.003.155`. If the person can no longer be served, such as a principal disabled since the session started, reads are served as the staff member and every change except ending the impersonation is refused with `CH.003.153`. A sign-in with no open impersonation session is a 404. The console reads it to show who it is impersonating. ## OpenAPI ````yaml /api-reference/openapi.yaml get /v3/me/impersonation openapi: 3.1.0 info: contact: email: support@ctrl-hub.com name: Ctrl Hub url: https://www.ctrl-hub.com description: > Ctrl Hub is the all-in-one platform for high-risk industries like utilities, construction, infrastructure, and renewables.
