# Mark Preview Queue Seen

`POST /api/v1/messages/preview-queue/mark-seen`

## Request

- Base URL: `https://api.nudgelink.co` (the document declares no server; this is the origin it was published from)
- URL: `https://api.nudgelink.co/api/v1/messages/preview-queue/mark-seen`
- Auth: HTTP bearer

Bump the Preview-queue read cursor to now.

Idempotent. Called by the frontend a few seconds after the page has
rendered (debounced) — not on every 10s auto-refresh poll — so the "new"
badge reflects messages the client hasn't actually had a chance to see
yet, the same way ``POST /inbox/conversations/{lead_id}/mark-read`` works
for the inbox tab.

## Response `200`

Successful Response

- MarkPreviewQueueSeenResponse
  - `seen_at` string, date-time, required
