# Registrations

> **BETA**

Endpoints for tracking and managing the registrations made against a Bookable Event.

#### Notes
Registrations can only be created or updated.

To remove a Registration from a Bookable Event, it is updated with a `status` of `declined` or `removed`. The latter can be acheived by the [Remove Registration](/developers/api/scheduling/bookable-events/registrations/delete/index.md) endpoint.
