Clear Read Notifications

Bulk-delete every read notification for the calling user. Returns the count actually deleted. Unread rows are untouched.

DELETE /api/v1/notifications/clear-read — 🔑 Bearer · Rate limit: 60 req / minute

Bulk-deletes every read notification (read = true) for the calling user via a single deleteMany. Unread rows are untouched. Returns the count actually deleted (zero is a normal result if nothing was read yet).

Hard delete, no undo. This is the bulk equivalent of DELETE /notifications/:id for read items. Once deleted, the rows are gone — no recycle bin. If you want to keep a "see all" feed, don't expose this as a one-click action; gate it behind a confirm dialog.

No filtering parameters. This endpoint deletes all read notifications. There is no "delete read older than N days" or "delete read for event X". For scoped deletes, iterate DELETE /:id per item from the filtered list.

Request

No body, no params. Identity comes from the bearer token.

Header	Required	Notes
`Authorization: Bearer <accessToken>`	✓	JWT from `POST /auth/login`

Response

`200 OK` — `ApiResponseOf<ClearReadResponseDto>`

{
  "success": true,
  "data": {
    "deleted": 12
  }
}

Field	Type	Notes
`deleted`	number	Count of read rows actually removed. `0` is a normal result.

Errors

HTTP	`code` / `i18nKey`	Reason
`401`	(guard)	Missing / invalid bearer token
`429`	(throttle)	Rate limit exceeded (60 req/min)

Side effects

prisma.notification.deleteMany({ where: { userId, read: true } }).
Return { deleted: result.count }.
Unread rows are not touched (filter excludes them).
