# List Types

GET /api/v2/projects/{projectId}/crm/notification-types

Lists the notification types a project has defined: the named categories, such as product updates or billing alerts, that contacts can subscribe to independently. Public and unauthenticated so a preference centre can render the available options before the contact is identified.

## Request

- includeSystemAttributes: boolean, query — Also return Saasco's built-in `$`-prefixed attributes (geo, device, subscription state) alongside your own custom ones.
