UserActor class

Represents the act (actor) claim from an ID token issued during a Custom Token Exchange delegation or impersonation flow.

The act claim identifies the acting party — the entity performing actions on behalf of the subject (for example, an AI agent or a support representative). It is set server-side via an Auth0 Action using the api.authentication.setActor() command.

The claim may be nested to represent delegation chains (act.act for multi-hop delegation); the full structure is preserved.
