# getAvailableNotificationTypes

The catalog of notification types you can filter by: each with its notificationType (the exact string to pass as notificationTypeFilter on listNotifications / getNotificationCounts), a human description, and a category. Call this first to filter reliably: notificationTypeFilter is a free string, so a typo silently returns an empty feed rather than an error.

- Call: `POST https://server.goliathdata.com/api/v1/call` with `{ "operationId": "getAvailableNotificationTypes", "variables": {...} }`
- Scope: `READ`
- Type: query
- Idempotency: a read; rejects `Idempotency-Key`
- Rate-limited: no
