Update Task task.item.update

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: task

Who can execute the method: any user

The method task.item.update updates task data. See the fields available for update. When task data is updated, business logic and permissions are taken into account. For example, a participant cannot rename a task; in this case, an error is returned.

It is recommended to check whether the action is allowed before updating the data (task.item.isactionallowed).

DEPRECATED

The development of this method has been discontinued. Use tasks.task.update.

Method Parameters

Name	Description
TASKID	Task identifier.
TASKDATA	List of fields with new values.

It is mandatory to follow the order of parameters in the request. If this order is violated, the request will be executed with errors.
