## Search SKUs

`POST /v1/catalog-skus/search`

Search parent products using the conditions passed in the request body.

Unlike [`GET /v1/catalog-skus`](./list.md), the `filter`, `select`, `sort`, `limit`, and `offset` parameters are passed in the JSON body rather than in the query string — conditions across several fields are expressed as a nested structure. Like the list, search requires `filter.iblockId` — without this field the request returns `400`. The response format is the same as for the list.

## Request fields (body)

| Parameter | Type | Required | Default | Description |
|----------|-----|:-----:|-----------|---------|
| `filter` | object | yes | — | Filtering conditions. The `iblockId` key is required — the product catalog ID from [`GET /v1/catalogs`](/docs/entities/catalogs). The `type` key accepts one exact number: `3` — parent products with offers, `6` — without offers.<br>[Filtering syntax](/docs/filtering). Example: `{ "iblockId": 25, "type": 3 }` |
| `select` | string[] | no | — | Field selection: `["iblockId", "id", "name", "type"]`. If the parameter is passed, it must include `iblockId` and `id`. Without `select`, the response carries a reduced set of fields: the symbolic code, texts, sort order, and external code are returned only when listed explicitly — [SKU fields](./fields.md) lists which ones. A catalog property is requested by its own name: `["iblockId", "id", "name", "property295"]` |
| `sort` | string | no | — | Sort field. The `-` prefix means descending: `"-id"` |
| `limit` | number | no | `50` | Number of records (up to 5000) |
| `offset` | number | no | `0` | Offset from the start of the result set. Combined with a date-range filter wider than 14 days, the request is rejected — see `UNSTABLE_OFFSET_PAGINATION` in the "Errors" section |
| `autoWindow` | boolean | no | `true` | Split the result set into weekly windows when filtering by a date range wider than 14 days. `false` disables splitting |

## Response fields

| Field | Type | Description |
|------|-----|---------|
| `success` | boolean | Always `true` on success |
| `data` | array | Array of parent products. For the fields of each item, see [SKU fields](./fields.md) |
| `meta.total` | number | Number of records matching the filter |
| `meta.hasMore` | boolean | Whether there are more records beyond `limit` |
| `meta.durationMs` | number | Request duration in milliseconds |
| `meta.autoWindowed` | boolean | `true` if the result set was split into time windows |
| `meta.windowCount` | number | Number of windows. Present with `autoWindowed: true` |
| `meta.batchWaves` | number | Number of parallel request waves. Present with `autoWindowed: true` |
| `meta.warnings` | array | Warnings about `select`. Present when `select` contains a name that is not in the field reference: an item `{ code: "UNKNOWN_SELECT_FIELD", message, field }`, and no value for that name is included in the response |

The `meta` fields sit next to `data`, not inside it. Paginate using `meta.hasMore`: a `data` array whose length equals `limit` can still be the last page.

## Response example

```json
{
  "success": true,
  "data": [
    {
      "id": 7205,
      "iblockId": 25,
      "iblockSectionId": 19,
      "name": "Basic hoodie",
      "type": 3,
      "active": true,
      "available": true,
      "bundle": false,
      "createdBy": 1295,
      "modifiedBy": 1295,
      "dateActiveFrom": null,
      "dateActiveTo": null,
      "dateCreate": "2026-10-08T18:45:34.000Z",
      "timestampX": "2026-10-08T18:45:36.000Z"
    },
    {
      "id": 7203,
      "iblockId": 25,
      "iblockSectionId": null,
      "name": "Basic T-shirt",
      "type": 3,
      "active": true,
      "available": true,
      "bundle": false,
      "createdBy": 1295,
      "modifiedBy": 1295,
      "dateActiveFrom": null,
      "dateActiveTo": null,
      "dateCreate": "2026-10-08T18:45:34.000Z",
      "timestampX": "2026-10-08T18:45:35.000Z"
    }
  ],
  "meta": {
    "total": 14,
    "hasMore": true,
    "durationMs": 140
  }
}
```

With a date-range filter wider than 14 days, `meta` additionally returns `autoWindowed`, `windowCount`, and `batchWaves`:

```json
{
  "success": true,
  "data": [ /* ... */ ],
  "meta": {
    "total": 12,
    "hasMore": true,
    "autoWindowed": true,
    "windowCount": 301,
    "batchWaves": 7,
    "durationMs": 4058
  }
}
```

## Error response example

400 — the required filter was not passed:

```json
{
  "success": false,
  "error": {
    "code": "MISSING_REQUIRED_FILTER",
    "message": "POST /v1/catalog-skus/search requires filter fields: iblockId. Example body: { \"filter\": {\"iblockId\":\"...\"} }"
  }
}
```

## Errors

| HTTP | Code | Description |
|------|-----|---------|
| 400 | `MISSING_REQUIRED_FILTER` | The required `filter.iblockId` filter was not passed. The request is rejected before Bitrix24 is called — the message contains the name of the missing field and a request body example |
| 400 | `UNSUPPORTED_FILTER` | The `filter.type` key was passed as something other than a single number `3` or `6` — another number, an operator, or an array |
| 422 | `BITRIX_ERROR` | `iblockId` points to an offer catalog (`productType is not allowed for this catalog`) |
| 422 | `BITRIX_ERROR` | `iblockId` is not a catalog (`iblock is not catalog`) |
| 422 | `BITRIX_ERROR` | `select` was passed without `iblockId` (`Required select fields: iblockId`) |
| 422 | `BITRIX_ERROR` | `select` was passed without `id` (`Required select fields: id`) |
| 400 | `UNKNOWN_FILTER_FIELD` | Filtering by a field the parent product does not have. The message contains the list of available fields |
| 400 | `UNKNOWN_SORT_FIELD` | Sorting by a field the parent product does not have. The message contains the list of available fields |
| 400 | `UNSTABLE_OFFSET_PAGINATION` | `offset` greater than zero together with a date-range filter wider than 14 days. Two different retrieval algorithms produce inconsistent results, so the request is rejected. Fetch everything in a single request with `limit` up to 5000, or pass `autoWindow: false` with sorting by `id`, or split the date range into parts yourself |
| 403 | `SCOPE_DENIED` | The API key does not have the `catalog` scope |
| 401 | `MISSING_API_KEY` | The `X-Api-Key` header was not passed |
| 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 |

## Known specifics

**Time-window splitting.** A date-range filter wider than 14 days is automatically split into weekly windows executed in parallel waves, so the result set bypasses the ceiling of 5000 records per call. `meta` then returns `autoWindowed: true`, the number of windows `windowCount`, and the number of waves `batchWaves`. The `autoWindow: false` parameter disables splitting. While splitting is active, an `offset` greater than zero is rejected with `UNSTABLE_OFFSET_PAGINATION`.
