## List knowledge base bindings to workgroups

`GET /v1/sites/group-bindings`

Returns knowledge base bindings to the Bitrix24 account's workgroups, all at once or for one group.

How a binding affects the site type is described in [Knowledge base bindings to a workgroup](/docs/entities/sites/group-binding).

## Parameters

| Parameter | Type | Required | Description |
|----------|-----|:-----:|----------|
| `groupId` (query) | number | no | Workgroup ID. List: `GET /v1/workgroups`. A positive integer. An empty value, zero or a non-numeric string returns `400 INVALID_PARAMS`. Without the parameter, bindings of all groups are returned |
| `scope` (query) | string | no | Site scope: `KNOWLEDGE`, `GROUP` or `MAINPAGE`. Any other value returns `400 INVALID_SCOPE` |

There is no pagination: the response contains all bindings matching the filter in a single array. The `limit` and `offset` parameters are ignored.

| `success` | boolean | Always `true` on success |
| `data` | array | Array of bindings. An empty array if no bindings match the filter |
| `data[].siteId` | number | Knowledge base site ID. Get the site: `GET /v1/sites/:id?scope=GROUP` |
| `data[].groupId` | number | Workgroup ID. Get the group: `GET /v1/workgroups/:id` |
| `data[].title` | string | Site title. An empty string if no title was returned |

## Response example

```json
{
  "success": true,
  "data": [
    {
      "siteId": 125,
      "groupId": 51,
      "title": "Knowledge base",
      "publicUrl": "https://example.bitrix24.com/knowledge/group/knowledge_base/"
    },
    {
      "siteId": 95,
      "groupId": 7,
      "title": "Support knowledge base",
      "publicUrl": "https://example.bitrix24.com/knowledge/group/support_knowledge_base/"
    }
  ]
}
```

## Error response example

400 — empty `groupId` value:

```json
{
  "success": false,
  "error": {
    "code": "INVALID_PARAMS",
    "message": "groupId must be a positive safe integer"
  }
}
```

## Errors

| HTTP | Code | Description |
|------|-----|----------|
| 400 | `INVALID_PARAMS` | `groupId` is passed but is not a positive integer, including an empty value |
| 400 | `INVALID_SCOPE` | `scope` is not `KNOWLEDGE`, `GROUP` or `MAINPAGE` |
| 422 | `BITRIX_ERROR` | Bitrix24 returned the list of bindings in an unexpected format |
| 403 | `BITRIX_ACCESS_DENIED` | Bitrix24 denied access to the key owner |
| 403 | `B24_TARIFF_RESTRICTION` | The portal plan does not allow the call |
| 403 | `SCOPE_DENIED` | The API key does not have the `landing` scope |
| 401 | `TOKEN_MISSING` | The API key has no configured tokens |
| 429 | `RATE_LIMITED` | Bitrix24 throttled requests to the portal. Retry after the delay from the `Retry-After` header |
| 502 | `BITRIX_UNAVAILABLE` | Bitrix24 responded with a server error or the connection dropped before a complete response. The request only reads data, so a retry is safe |
| 503 | `BITRIX_TIMEOUT` | Bitrix24 did not respond in time. The request only reads data, so a retry is safe |

## Known specifics

**The list contains only site bindings.** Bindings of individual knowledge base pages to a group are not included in the response, so `siteId` always points to a site, not a page.
