## Value fields

`GET /v1/catalog-product-property-enums/fields`

Returns the field reference of an enumeration element with types and the read-only flag, plus the operations available in a batch request.

The response is assembled from the static entity schema — Bitrix24 is not called.

## Examples

### curl — personal key

```bash
curl "https://vibecode.bitrix24.com/v1/catalog-product-property-enums/fields" \

### JavaScript — personal key

```javascript

## Response fields

`data.fields` is an object whose key matches the field name and whose value carries `type`, `readonly`, and the human-readable `label` and `description`. `data.batch` lists the **write** operations available in a [batch request](/docs/batch); for this entity it is empty, because there is no write path at all. That does not rule out reads in a batch: the `list` and `get` sub-calls through [`POST /v1/batch`](/docs/batch) and `POST /v1/catalog-product-property-enums/batch` work. The `fields` sub-call is accepted in a batch too, but for this entity it answers `200` with an **empty object** — Bitrix24 is not called and the field reference cannot be obtained that way. Take it from the single `GET /v1/catalog-product-property-enums/fields`.

| Field | Type | RO | Description |
|------|-----|:--:|---------|
| `id` | number | yes | Identifier of the enumeration element. This is the value a [catalog product](/docs/entities/catalog-products) carries in `propertyNNN.value` |
| `propertyId` | number | yes | Identifier of the owning property. Required in the list and search filter |
| `value` | string | yes | Readable text of the option — the same text a product returns in `propertyNNN.valueEnum` |
| `def` | boolean | yes | Whether this option is the property's default value |
| `sort` | number | yes | Sort index within the property |
| `xmlId` | string | yes | External code. Comes back as `null` when not set |

| Field | Type | Description |
|------|-----|---------|
| `success` | boolean | Always `true` on success |
| `data.fields.<name>.type` | string | Field type: `number`, `string`, `boolean` |
| `data.fields.<name>.readonly` | boolean | `true` for every field of this entity |
| `data.fields.<name>.label` | string | Human-readable field name |
| `data.fields.<name>.description` | string | Explanation of the field |
| `data.batch` | string[] | Write operations available in a [batch request](/docs/batch). For this entity — an empty array; read sub-calls still work |

## Response example

`label` and `description` are shown for the first field only and omitted for the rest for brevity.

```json
{
  "success": true,
  "data": {
    "fields": {
      "id": {
        "type": "number",
        "readonly": true,
        "label": "ID",
        "description": "Identifier of the enumeration element. This is the value that a product's propertyNNN.value carries."
      },
      "propertyId": { "type": "number", "readonly": true },
      "value": { "type": "string", "readonly": true },
      "def": { "type": "boolean", "readonly": true },
      "sort": { "type": "number", "readonly": true },
      "xmlId": { "type": "string", "readonly": true, "nullable": true }
    },
    "batch": []
  }
}
```

## Error response example

403 — no scope:

```json
{
  "success": false,
  "error": {
    "code": "SCOPE_DENIED",
    "message": "This endpoint requires 'catalog' scope"
  }
}
```

## Errors

| HTTP | Code | Description |
|------|-----|---------|
| 403 | `SCOPE_DENIED` | The API key does not carry the `catalog` scope |
| 401 | `MISSING_API_KEY` | The `X-Api-Key` header was not sent |

## Known specifics

**The entity is read-only.** List options are created in the Bitrix24 interface. `POST`, `PATCH`, `DELETE`, and `POST /aggregate` are not registered and answer `404`, and `data.batch` comes back as an empty array. Read sub-calls in a [batch request](/docs/batch) remain available.

**Only properties of type `L` have an enumeration.** For a property of any other type (`S`, `N`, `F`, `E`, `G`) the option list is empty. The property type is read from [`GET /v1/catalog-product-properties/:id`](/docs/entities/catalog-product-properties/get) in the `propertyType` field.

**The link to product fields.** A list-property value arrives on a [catalog product](/docs/entities/catalog-products) in the field `propertyNNN`, where `NNN` is the property `id`. Inside are `value` (the enumeration element id, as a string), `valueEnum` (the ready-made text), and `valueId` (the value row id). Match with `String(element.id) === product.propertyNNN.value`.
