# Create a deadline event in your own GCal · 0 credits

`POST /api/v1/gcal/events/plazo`

## Request

- Base URL: `https://legal.nexusquantum.legal`
- URL: `https://legal.nexusquantum.legal/api/v1/gcal/events/plazo`
- Auth: HTTP bearer

Creates an all-day deadline event in the USER'S OWN Google Calendar (`createCalendarEvent(userId, …)`), idempotent on `(user_id, fecha_base, fecha_vencimiento, preset_slug)`. Returns `{ status, google_event_id }` (no token). `502 GCAL_NOT_CONNECTED_OR_FAILED` verbatim if the user has no GCal connected. Thin loopback to `/api/gcal/events/plazo` (adopted to `requireUser`, `checkSameOrigin` untouched). No charge. Scope: mcp | *. API-only (side effect, no MCP tool).

## Request body

- object
  - `preset_slug` string
  - `label` string
  - `fecha_base` string
  - `fecha_vencimiento` string
  - `regla_aplicable` string
  - `case_name` string

## Response `200`

{ status, google_event_id }

- object

## Other responses

- `401`: Invalid or missing API key.
- `403`: INSUFFICIENT_SCOPE — the key lacks scope mcp | *.
- `502`: GCAL_NOT_CONNECTED_OR_FAILED — no GCal connected, or the event could not be created.
