## List sections

`GET /v1/product-sections`

Returns product catalog sections with filtering and auto-pagination support. These are the same sections available via [`GET /v1/catalog-sections`](/docs/entities/catalog-sections) — with the same `id`.

## Parameters

| Parameter | Type | Default | Description |
|----------|-----|-----------|---------|
| `limit` | number | `50` | Number of records up to 5000. When `limit > 50` Vibecode automatically requests several pages from Bitrix24 |
| `offset` | number | `0` | Offset from the start of the selection |
| `select` | string | — | Field selection: `?select=id,name,sectionId` |
| `filter` | object | — | Exact-match and `$in` (IN set) only, by `id`, `name`, `xmlId`, `code`, `catalogId`, `sectionId`. Operators (`>`, `>=`, `<`, `<=`, `!`, `%`, `$ne`, `$contains`, `$nin`) and filtering by `sort` are not supported — you get `400 UNSUPPORTED_FILTER`.<br>[Filtering syntax](/docs/filtering). Example: `?filter[catalogId]=25` |

## Response fields

| Field | Type | Description |
|------|-----|---------|
| `success` | boolean | Always `true` on success |
| `data` | array | Array of sections |
| `data[].id` | number | Section identifier |
| `data[].name` | string | Section name |
| `data[].catalogId` | number | ID of the catalog the section belongs to |
| `data[].sectionId` | number | Parent section ID. `null` for a top-level section |
| `data[].code` | string | Section symbolic code |
| `data[].xmlId` | string | External identifier |
| `meta.total` | number | Total number of records matching the filter |
| `meta.hasMore` | boolean | Whether more records exist beyond `limit` |

The `sort` field is not included in the list and cannot be filtered by (it does work in `order`/`sort`). Full section field set — [`GET /v1/product-sections/fields`](./fields.md).

## Response example

```json
{
  "success": true,
  "data": [
    {
      "id": 31,
      "catalogId": 25,
      "sectionId": null,
      "name": "Clothing",
      "code": "clothes",
      "xmlId": "666"
    },
    {
      "id": 45,
      "catalogId": 25,
      "sectionId": null,
      "name": "Winter collection",
      "code": "winter",
      "xmlId": null
    }
  ],
  "meta": {
    "total": 36,
    "hasMore": true
  }
}
```

## Error response example

403 — no scope:

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

## Errors

| HTTP | Code | Description |
|------|-----|---------|
| 400 | `UNSUPPORTED_FILTER` | An operator or a non-filterable field in the filter. Filter by exact match or `$in` on `id`, `name`, `xmlId`, `code`, `catalogId`, `sectionId` |
| 400 | `INVALID_FILTER` | Error in filter syntax |
| 403 | `SCOPE_DENIED` | Key is missing the `crm` scope |
| 401 | `MISSING_API_KEY` | The `X-Api-Key` header was not provided |

## Known specifics

**Exact match only.** The filter applies exact match (and `$in` set) on `id`, `name`, `xmlId`, `code`, `catalogId`, `sectionId`. Operators (`>`, `<`, `!`, `%`), `$ne`/`$contains`/`$nin` and filtering by `sort` return `400 UNSUPPORTED_FILTER` — so you see immediately that the filter did not apply, instead of getting the whole list unfiltered.

**Sections of one parent.** To get nested sections inside a specific section, filter by exact match on `filter[sectionId]` with the parent identifier.

**Without a filter, sections of all catalogs in your Bitrix24 account are returned.** To limit the selection to a single catalog, pass `filter[catalogId]`. Catalog list — `GET /v1/catalogs`.
