# Admin Set Campaign First Ux

`POST /api/v1/admin/clients/{client_id}/set-campaign-first-ux`

## 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/admin/clients/{client_id}/set-campaign-first-ux`
- Auth: HTTP bearer

Flip a client onto (or off) the campaign-first UX. Sets/clears
``campaign_first_ux_at`` — the timestamp is both the switch and the rollout
audit trail (when each client was migrated). Reversible: enabled=false → NULL
→ the client falls back to the legacy UX (all data changes are additive, so
nothing else needs reverting). Audit-logged.

## Path parameters

- `client_id` string, uuid, required

## Request body

- SetCampaignFirstRequest
  - `enabled` boolean, required

## Response `200`

Successful Response

- SetCampaignFirstResponse
  - `client_id` string, uuid, required
  - `campaign_first_ux` boolean, required
  - `campaign_first_ux_at` string, date-time, nullable, required

## Other responses

- `422`: Validation Error
