## Create an offer

`POST /v1/catalog-offers`

Creates a product offer in the offers catalog and links it to a parent product. Fields are passed flat at the JSON root.

## Request fields (body)

| Field | Type | Required | Description |
|------|-----|:-----:|---------|
| `name` | string | yes | Offer name |
| `iblockId` | number | yes | Offers catalog ID — the catalog that has `productIblockId` set. List: `GET /v1/catalogs` |
| `parentId` | object | no | Link to the parent product: `{ "value": "<ID>" }`, with the ID as a string. List: `GET /v1/catalog-skus`. Without this field, a free offer with `type: 5` is created |
| `active` | boolean | no | Whether the offer is active. Defaults to `true` |
| `iblockSectionId` | number | no | Catalog section ID. List: `GET /v1/catalog-sections` |
| `measure` | number | no | Unit of measure ID. List: `GET /v1/catalog-measures` |
| `weight` | number | no | Weight of one product unit |
| `vatIncluded` | boolean | no | VAT included in the price |
| `canBuyZero` | boolean | no | Allow purchase when stock is zero |
| `quantityTrace` | boolean | no | Enable quantity tracking |
| `subscribe` | boolean | no | Allow subscription to the product |
| `barcodeMulti` | boolean | no | Separate barcodes for product units |
| `withoutOrder` | boolean | no | Available for ordering without stock on hand |
| `purchasingPrice` | number | no | Purchase price |
| `purchasingCurrency` | string | no | Purchase price currency. List: `GET /v1/currencies` |
| `quantity` | number | no | Stock on hand |

The symbolic code, dimensions, texts, images and catalog properties `propertyNNN` are listed in [Offer fields](./fields.md). The selling price is set separately — in [`POST /v1/catalog-prices`](/docs/entities/catalog-prices/create) with the offer `id` in `productId`.

## Error response example

400 — a required field was not passed:

```json
{
  "success": false,
  "error": {
    "code": "MISSING_REQUIRED_FIELDS",
    "message": "Body field \"name\" is required to create catalogOffer."
  }
}
```

## Errors

| HTTP | Code | Description |
|------|-----|----------|
| 400 | `MISSING_REQUIRED_FIELDS` | A required field was not passed — the message names it. An empty body is rejected with a message about `iblockId` |
| 400 | `READONLY_FIELD` | The body contains a read-only field, for example `available` |
| 422 | `BITRIX_ERROR` | No parent product with the ID from `parentId` exists (`Parent product not found.`) |
| 422 | `BITRIX_ERROR` | `iblockId` holds the ID of a product catalog, not an offers catalog (`productType is not allowed for this catalog`) |
| 422 | `BITRIX_ERROR` | No catalog with the specified `iblockId` exists (`iblock is not catalog`) |
| 403 | `SCOPE_DENIED` | The key lacks the `catalog` scope |
| 401 | `MISSING_API_KEY` | The `X-Api-Key` header was not passed |
