## Unbind knowledge-base menu bindings

`DELETE /v1/sites/:id/menu-bindings/:menuCode`

Writes change interface menus for ALL employees of the Bitrix24 account. Only KNOWLEDGE sites are supported. Menu codes are internal Bitrix24 codes such as crm_switcher:lead; discover existing codes with GET /v1/sites/menu-bindings. Bitrix24 provides no other catalogue.

Requires landing key scope. Every route accepts optional query scope=KNOWLEDGE|GROUP|MAINPAGE. Bitrix24 selects its binding context; pre-read searches KNOWLEDGE, then GROUP and the supplied or default context.

## Parameters

| Parameter | Type | Required | Description |
|---|---|---|---|
| id | integer | yes | Positive safe site ID from GET /v1/sites |
| menuCode | string | yes | Non-empty internal menu code |
| scope | string | no | KNOWLEDGE / GROUP / MAINPAGE |

No body. URL-encode colons in menuCode: crm_switcher%3Alead.

## curl

```bash
curl -X DELETE "https://vibecode.bitrix24.com/v1/sites/42/menu-bindings/crm_switcher%3Alead" -H "X-Api-Key: YOUR_API_KEY"
```

## JavaScript

```javascript
const response = await fetch("https://vibecode.bitrix24.com/v1/sites/42/menu-bindings/crm_switcher%3Alead", {
  method: "DELETE",
  headers: { "X-Api-Key": "YOUR_API_KEY" },
});
const result = await response.json();
```

## Response

```json
{
  "success": true,
  "data": []
}
```

READONLY rejects writes before Bitrix24. false returns 422 with possible reasons; true reads bindings back and, for groups, the site with its new type. Rebinding or removing a missing binding can also return false.
