Delete Notification

Hard-delete a single notification by id. Ownership-checked. There is no recycle bin or undo flow.

DELETE /api/v1/notifications/:id — 🔑 Bearer · Rate limit: 60 req / minute

Hard-deletes a single notification row. Ownership is enforced via findFirst({ id, userId }); missing or cross-user lookups return 404 not_found (same code — no enumeration leak).

Hard delete, no undo. Once gone, the row is gone — there's no recycle bin or "deleted" flag. To bulk-clear notifications you've already read, use DELETE /notifications/clear-read instead (covered in Batch 2).

Request

Path parameters

Param	Type	Validation	Notes
`id`	string (UUID)	`ParseUUIDPipe`	The notification to delete

No body.

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

Response

`200 OK` — `SuccessOnlyResponseDto`

{
  "success": true
}

Field	Type	Notes
`success`	boolean	Always `true` on 200

Errors

HTTP	`code` / `i18nKey`	Reason
`400`	(validation)	`id` not a valid UUID
`401`	(guard)	Missing / invalid bearer token
`404`	`error.notification.not_found`	Notification not found OR belongs to a different user (same code on purpose)
`429`	(throttle)	Rate limit exceeded (60 req/min)

Side effects

Ownership-aware lookup — prisma.notification.findFirst({ where: { id, userId } }). Returns null for missing OR cross-user → throw not_found.
prisma.notification.delete({ where: { id } }).
Return { success: true }.
