# Create a checkin

`POST /v1/checkins`

## Request

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

Creates an intake/inspection record for an existing vehicle.

Required body fields: `customer_id`, `vehicle_id`. Everything
else is optional. The server assigns `id`, `company_id` (from
the authenticated user), `created_by`, `seq_number`, timestamps,
and an initial `status` of `"active"`.

Line-item creation is out of scope for v1 — a created checkin
starts with an empty `line_items` array. The response is the
fully materialized post-create entity (same shape as
`GET /v1/checkins/{id}`).

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

## Request body

- CheckinCreateRequest: Body of `POST /v1/checkins`. Server-managed fields (`id`, `company_id`, `created_by`, `seq_number`, `status`, timestamps) are NOT accepted. Line items start empty — a dedicated sub-resource will land later.
  - `customer_id` string, required
  - `vehicle_id` string, required
  - `title` string, nullable
  - `comments` string, nullable
  - `internal_comments` string, nullable
  - `work_category_id` string, 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.
  - `fuel_level` integer, nullable
  - `section1` string, nullable
  - `section2` string, nullable
  - `section3` string, nullable
  - `section4` string, nullable
  - `section5` string, nullable
  - `section6` string, nullable
  - `section7` string, nullable
  - `section8` string, nullable
  - `km` number, nullable

## Response `201`

Checkin created.

- Checkin: A vehicle intake / inspection snapshot. Belongs to one company, one customer, and one vehicle. List responses omit `line_items` to keep payloads small; detail responses populate it.
  - `object` 'checkin', required
  - `id` string, required
  - `seq_number` integer, required: Per-company human-readable sequence (e.g. "Checkin #142"). Assigned at create time and stable afterwards.
  - `status` 'active' | 'completed', required: Lifecycle state. Mutated only through `POST /v1/checkins/{id}/transitions`, never via PATCH.
  - `title` string, nullable
  - `comments` string, nullable
  - `internal_comments` string, nullable: Notes visible only to workshop staff.
  - `customer_id` string, required
  - `vehicle_id` string, required
  - `work_category_id` string, nullable
  - `worksheet_id` string, nullable: Set when the checkin has been converted into a worksheet.
  - `quote_id` string, nullable: Set when the checkin has been converted into a quote.
  - `fuel_level` integer, nullable: Free-form integer captured at intake. Convention is 0–100 (percentage) but the API enforces no bounds today.
  - `section1` string, nullable
  - `section2` string, nullable
  - `section3` string, nullable
  - `section4` string, nullable
  - `section5` string, nullable
  - `section6` string, nullable
  - `section7` string, nullable
  - `section8` string, nullable
  - `km` number, nullable: Odometer reading at intake.
  - `created_by` string, required: User id of the staff member who created the checkin.
  - `customer_name` string, required: Denormalized display string of the linked customer. Pre-computed on the entity for list-row rendering without a second request.
  - `vehicle_name` string, required: Denormalized display string of the linked vehicle.
  - `vehicle_license` string, nullable
  - `work_category_name` string, nullable
  - `work_category_ids` string[], required: Every work category ("categoria") of the document, in the order chosen. `work_category_id` (kept for clients that handle a single category) always equals the first. `[]` when the document has none, never null. Available since revision 2026-10-03.
  - `work_categories` WorkCategory[], required: The same list as `work_category_ids` with each category's name, same order. `work_category_name` is the first one's name. Available since revision 2026-10-03.
    - `object` 'work_category', required
    - `id` string, uuid, required
    - `name` string, required
  - `delivered_at` string, date-time, nullable
  - `created_at` string, date-time, required
  - `updated_at` string, date-time, required
  - `deleted_at` string, date-time, nullable: Soft-deletion timestamp. Populated on the response from DELETE /v1/checkins/{id}. Checkins with a non-null deleted_at are not returned by list/detail endpoints — this field appears for the delete response only.
  - `line_items` CheckinLineItem[], nullable: Embedded line items (description-only notes). Populated on detail / batch responses; list GET emits `null` to keep payloads small. Mutate via POST /v1/checkins/{id}/line-items/batch.
    - `object` 'checkin_line_item', required
    - `id` string, required
    - `description` string, required
    - `created_at` string, date-time, required
