Transfer a Dialogue to an Operator or Queue using imopenlines.bot.session.transfer

If you are developing integrations for Bitrix24 using AI tools (Codex, Claude Code, Cursor), connect to the MCP server so that the assistant can utilize the official REST documentation.

Scope: imopenlines, imbot

Who can execute the method: application user with a registered chat bot

The method imopenlines.bot.session.transfer transfers a dialogue from the chat bot in an open line to a specified operator or queue.

Method Parameters

Required parameters are marked with *

Name `type`	Description
CHAT_ID* `integer`	The identifier of the chat whose dialogue needs to be transferred. The chat identifier can be obtained using the methods imopenlines.dialog.get or imopenlines.crm.chat.get
USER_ID `integer`	The identifier of the employee to whom the dialogue should be transferred. The user identifier can be obtained using the methods user.get or user.search
QUEUE_ID `integer`	The identifier of the queue to which the dialogue should be transferred. Pass the value of the `ID` field from the response of the method imopenlines.config.list.get. The `QUEUE` field from the response of imopenlines.config.list.get contains `USER_ID` of the employees in the queue and is not suitable as `QUEUE_ID`
TRANSFER_ID `string`\|`integer`	Universal transfer destination parameter. Allowed formats: `USER_ID` of the employee or the string `queue<QUEUE_ID>`. The user identifier can be obtained using the methods user.get and user.search, and the queue identifier can be obtained using the method imopenlines.config.list.get
LEAVE `boolean`	Flag indicating the presence of the chat bot in the dialogue after the transfer. Allowed values: `Y` — the bot leaves the chat immediately `N` — the bot stays until the transfer is confirmed By default, `N` is used
CLIENT_ID `string`	This parameter is mandatory only for webhooks. Pass: the same `CLIENT_ID` that was specified when registering the chat bot using the method imbot.register or the value of the `botToken` parameter passed during the registration of the chat bot using the method imbot.v2.Bot.register

It is recommended to pass only one destination parameter: USER_ID, QUEUE_ID, or TRANSFER_ID. If multiple parameters are passed simultaneously, the method uses the following priority: USER_ID -> QUEUE_ID -> TRANSFER_ID. When passing TRANSFER_ID, the method converts it to USER_ID or QUEUE_ID.
