# Create a calendar entry

`POST /v1/calendar-entries`

## Request

- Base URL: `https://api.officina.it`
- URL: `https://api.officina.it/v1/calendar-entries`
- Auth: HTTP bearer

Creates an appointment owned by the authenticated user inside
their company. `end_time` must be strictly after `start_time`.
The response is the fully materialized entry (denormalized
customer / vehicle / calendar / user fields included) so the
client can render the new row without a follow-up GET.

Foreign-key references in the body (`customer_id`, `vehicle_id`,
`worksheet_id`, `work_category_id`, `calendar_id`) must resolve
to resources owned by the authenticated user's company.
Unreachable refs return 422 `parameter_invalid` pointing at the
offending field.

`worksheet_id` links the appointment to a scheda lavoro. Omit
`customer_id` / `vehicle_id` to take them from the worksheet;
when sent, they must be the worksheet's (a worksheet without a
vehicle fits any vehicle of its customer), otherwise the request
returns 422 `parameter_invalid` on `/worksheet_id`. Sending
`worksheet_id` needs `worksheets.read` (the key's scope, or the
app user's permission); without it the request returns 403.

## Request body

- CalendarEntryCreateRequest: Body of `POST /v1/calendar-entries`. `end_time` must be strictly after `start_time`. `user_id` (ownership), `company_id`, and audit timestamps are server-managed and not accepted on the wire. `worksheet_id` links the appointment to a scheda lavoro. `customer_id` and `vehicle_id`, when sent, must be the worksheet's (a worksheet without a vehicle fits any vehicle of its customer); when omitted they are taken from the worksheet. A mismatch returns 422 `parameter_invalid` on `/worksheet_id`. `quote_id` / `checkin_id` are response-only: the underlying repository does not persist them on create today, so they are intentionally absent from this request.
  - `title` string, required
  - `description` string, nullable
  - `start_time` string, date-time, required: RFC 3339 timestamp supplied by the client. Must fall between 1900-01-01 and 2100-12-31. A year outside that window is a typo (2025 mistyped as 0025 is the common one), and the app's own date pickers refuse the same range — a record written with one would not be editable in the web UI afterwards. Out of range → 422 `parameter_invalid` with `param` pointing at the offending field.

  - `vehicle_id` string, uuid, nullable
  - `worksheet_id` string, uuid, nullable
  - `work_category_id` string, uuid, nullable: Single-category form, accepted in every revision: the document's only category. To set several, send `work_category_ids` instead (not both).
  - `work_category_ids` string[]: The document's work categories, in the order chosen (`work_category_id` in responses reports the first). Trimmed and de-duplicated (first occurrence wins); at most 10, each one of the company's categories (`GET /v1/work-categories`) — an unknown id is reported on `/work_category_ids/{i}`. Do not send together with `work_category_id`: both → `422 parameter_invalid`. Available since revision 2026-10-03.
  - `calendar_id` string, uuid, nullable
  - `auto_reminder_enabled` boolean
  - `auto_reminder_channel` 'email' | 'sms' | 'whatsapp' | 'null', nullable
