## Update a command

`PATCH /v1/bots/:botId/commands/:commandId`

Updates the parameters of an existing command. Vibecode accepts a flat format and automatically wraps it into `fields` for Bitrix24.

## Request fields (body)

| Parameter | Type | Description |
|----------|-----|---------|
| `command` | string | New command text without `/` |
| `title` | string/object | New title. A string or `{ "ru": "...", "en": "..." }`. Passing `null` for a key removes the translation: `{ "en": null }` |
| `params` | string/object | New parameters description. A string or an object |
| `common` | string | `"Y"` / `"N"` |
| `hidden` | string | `"Y"` / `"N"` |
| `extranetSupport` | string | `"Y"` / `"N"` |

## Known specifics

**Removing a translation:** pass `null` for a language key: `{ "title": { "en": null } }` — removes the English translation while keeping the rest.

**String flags:** `common`, `hidden`, `extranetSupport` accept the strings `"Y"` / `"N"` (not boolean).
