Create a Group Chat imbot.v2.Chat.add

Choose a tool for developing with an AI agent:

use Alaio Vibecode to build an app for Bitrix24 from a task description without knowing any programming language. The agent writes the code and deploys the app to a server, with no manual hosting setup
use the MCP server to develop a REST API integration in your own project. The agent refers to the official REST documentation

Scope: imbot

Who can execute the method: owner of the registered bot

The method imbot.v2.Chat.add creates a group chat on behalf of the bot and adds the bot as a participant.

To send messages to the created chat, pass result.chat.dialogId from the response to the dialogId parameter of the Messages group methods.

Method Parameters

Required parameters are marked with *

Name `Type`	Description
botId* `integer`	Bot ID
botToken `string`	Bot token. Required for webhook authorization, not needed for OAuth. Pass the same `botToken` that you specified when registering the bot
fields `object`	Properties of the chat being created (detailed description)

Parameter fields

Name `Type`	Description
type `string`	Chat type: `chat` — a private group chat, default `open` — an open chat that any employee can join With any other value, the method creates a private chat
title `string`	Chat title
description `string`	Chat description
color `string`	Chat color — available colors. If not specified or incorrect, it will be assigned automatically
avatar `file`	Chat avatar in Base64 format
userIds `integer[]`	Array of participant IDs. You do not need to pass the bot — it is added to the chat automatically
ownerId `integer`	ID of the chat owner, the bot by default. The owner is automatically added to the chat as a participant and a manager. The method does not check whether the user exists: with a non-existent ID, the chat is created without an error and is left without an owner

Error Handling

HTTP Status: 400

{
            "error": "BOT_NOT_FOUND",
            "error_description": "Bot not found"
        }

Name `type`	Description
error `string`	String error code. It consists of digits, Latin letters, and underscores. It may arrive empty — in that case only `error_description` shows the reason
error_description `string`	Error message for the developer. Do not show it to the end user without processing

Possible Error Codes

Code	Description	Value
`BOT_TOKEN_NOT_SPECIFIED`	Bot token not specified (botToken is required for webhook auth)	`botToken` is not specified. Required for webhook authorization
`BOT_ID_REQUIRED`	botId is required	`botId` is not specified
`BOT_NOT_FOUND`	Bot not found	Bot not found
`BOT_OWNERSHIP_ERROR`	Bot was installed by another rest application	The bot is registered by another application
`ACCESS_DENIED`	ACCESS_DENIED	No permission to create chats
`CREATION_ERROR`	Error creating chat	Failed to create the chat

Statuses and System Error Codes

HTTP Status: 4xx, 5xx

The errors described below are returned by the REST API itself, not by the logic of a specific method. They can arrive in response to any method.

Status	Code Error Message	Description
`500`	`INTERNAL_SERVER_ERROR` Internal server error	An internal server error has occurred. Retry the call, and if the error persists, contact the server administrator or Bitrix24 technical support
`500`	`ERROR_UNEXPECTED_ANSWER` Server returned an unexpected response	The server returned an unexpected response. Retry the call, and if the error persists, contact the server administrator or Bitrix24 technical support
`503`	`QUERY_LIMIT_EXCEEDED` Too many requests	The request intensity limit has been exceeded
`429`	`OPERATION_TIME_LIMIT` Method is blocked due to operation time limit	The method is blocked because the request resource intensity limit has been exceeded. The block is lifted automatically once the accumulated execution time of the method no longer exceeds the limit
`401`	`NO_AUTH_FOUND` Wrong authorization data	The request contains no authorization data: neither an access token nor a webhook code was passed
`401`	`INVALID_REQUEST` Https required	Methods are called over the HTTPS protocol only
`401`	`OVERLOAD_LIMIT` REST API is blocked due to overload	The REST API is blocked due to overload. This is a manual individual block. To have it lifted, contact Bitrix24 technical support
`401`	`ACCESS_DENIED` REST is available only on commercial plans	REST API access is not active for this account. In Bitrix24 Cloud, check the current plan or trial status: Vibe+ plans include REST API access, while Essentials plans do not. A webhook receives a different error message — `REST is available only by subscription`
`401`	`INVALID_CREDENTIALS` Invalid request credentials	No active webhook with the specified user identifier and secret code was found

`401`	`user_access_error` The user does not have access to the application	The application is installed, but the Bitrix24 administrator has granted access to it only to specific users
