## Response fields

| Field | Type | Description |
|------|-----|---------|
| `success` | boolean | Always `true` on success |

| `data.fields.<field>.type` | string | Value type: `number`, `string`, `datetime` |
| `data.fields.<field>.readonly` | boolean | `true` means the field is set by the system; passing it on create or update is rejected with `400 READONLY_FIELD` |
| `data.fields.<field>.required` | boolean | Present only on fields required at creation, always with the value `true` |
| `data.fields.<field>.readonlyOnUpdate` | boolean | Present only on fields that are set at creation and cannot be changed on update, always with the value `true`. Passing such a field to [`PATCH /v1/shipment-items/:id`](./update.md) is rejected with `400 READONLY_FIELD` |
| `data.fields.<field>.label` | string | Short field name |
| `data.fields.<field>.description` | string | Field explanation |
| `data.aggregatable` | array | Fields allowed in [shipment item aggregation](./aggregate.md): as the field of a numeric function and as a `groupBy` grouping field |
| `data.batch` | array | Operations available in [batch operations on shipment items](./batch.md): `create`, `update`, `delete` |

### Shipment item fields

The full set of fields returned by `GET /v1/shipment-items/fields`. The RO column marks read-only fields.

| Field | Type | RO | Description |
|------|-----|:--:|---------|
| `id` | number | yes | Shipment item ID |
| `orderDeliveryId` | number | no | Shipment ID. List: [`GET /v1/shipments`](/docs/entities/shipments/list). Required at creation. Set only at creation: on update it is rejected with `400 READONLY_FIELD`, marked `readonlyOnUpdate` in the schema |
| `basketId` | number | no | ID of a basket item of the same order. List: [`GET /v1/basket-items`](/docs/entities/basket-items/list). Required at creation. Set only at creation: on update it is rejected with `400 READONLY_FIELD`, marked `readonlyOnUpdate` in the schema |
| `quantity` | number | no | Quantity of the product in the shipment; fractional values are allowed, for example `0.75`. Required at creation and in every [update](./update.md): a `PATCH` without `quantity` is rejected with `422 BITRIX_ERROR` |
| `reservedQuantity` | number | yes | Reserved quantity |
| `xmlId` | string | no | External code of the item |
| `dateInsert` | datetime | yes | Creation date in ISO 8601 format, for example `2026-10-07T09:55:27.000Z` |

## Error response example

```json
{
  "success": false,
  "error": {
    "code": "MISSING_API_KEY",
    "message": "API key required. Pass via X-Api-Key header."
  }
}
```

## Errors

| 401 | `MISSING_API_KEY` | The `X-Api-Key` header is not passed |
| 401 | `INVALID_API_KEY` | The passed API key was not found |
| 401 | `TOKEN_MISSING` | The API key has no configured tokens |
| 429 | `RATE_LIMITED` | Rate limit exceeded: 300 requests per minute per portal, all API keys of the portal share one limit. The exact value arrives in the `x-ratelimit-limit` header (the cap is divided across replicas). Retry after the delay in the `Retry-After` header |
