# Management App (Level 1)

A **Level 1** integration links your membership management system to XS4 Face
Cloud so that you can add, update, query and remove the users who are entitled
to use face recognition at a site.

The [Users API](_api) covers the whole of that lifecycle. Enrollment itself —
terms of service, image capture and consent — is handled either by the Salto
Enrollment App or, for a [Level 2](../introduction/#level-2---enrolling-users)
integration, by the [Enrollment API](../app/_api).
