# Selection Rules

> **ALPHA**

Selection Rules are a powerful feature used to resolve who should attend a Scheduling Request.
For example, a rule could describe that a Scheduling Request needs to select someone from the Engineers group, and 2 people from the Culture-fit interviewers group for a particular event.

These API endpoints enable reading and updating the state of Selection Rules; useful to keep Selection Rules in sync with your internal directory groups, or to automate adding and removing people to an interviewing rota.

These endpoints are authenticated via the `client_secret` of an [Internal Application](/developers/application-management/internal-applications/index.md) linked to your Organizational Unit.
