Unregister Chat Application imbot.app.unregister

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: imbot

Who can execute the method: any user

The method imbot.app.unregister removes the application from the chat.

Method Parameters

Name	Example	Description
APP_ID	`13`	Identifier of the application to be removed

This example uses the restCommand function. This is a method for sending data to Bitrix24. You can use your own function to call the method, the JavaScript method BX24.callMethod or industry standard B24PhpSDK.

How to Use Examples in Documentation

$result = restCommand(
            'imbot.app.unregister',
            Array(
                'APP_ID' => 13,
            ),
            $_REQUEST["auth"]
        );

Response on Success

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	The REST API is available only on commercial plans. 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
`404`	`ERROR_METHOD_NOT_FOUND` Method not found!	No method with this name was found. The name is misspelled, the method does not exist in the REST API, or it is unavailable without the required scope
`401`	`insufficient_scope` The request requires higher privileges than provided by the webhook token	The request requires broader permissions than the token has: for a webhook these are the permissions granted to it, for an application it is the scope. For an application, the error message ends with `provided by the access token`
`401`	`expired_token` The access token provided has expired	The access token has expired
`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
`403`	`PORTAL_DELETED` Portal was deleted	The public part of the site is closed. To open it on an on-premise installation, disable the "Temporary closure of the public part of the site" option. Path to the setting: Desktop > Settings > Product Settings > Module Settings > Main Module > Temporary closure of the public part of the site
