Update Comment `task.commentitem.update`

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: task

Who can execute the method: administrator

The method task.commentitem.update updates a comment.

DEPRECATED

The development of this method has been halted since version tasks 25.700.0. The method task.commentitem.update does not work in the new task card; use the method im.message.update for working with task chat.

Method Parameters

TASKID* `integer`	Task identifier. The task identifier can be obtained when creating a new task or by using the get task list method.
ITEMID* `integer`	Comment identifier. The comment identifier can be obtained when adding a new comment or by using the get comment list method.

Message text

UF_FORUM_MESSAGE_DOC
array

Array of file identifiers from Drive. Prefix each identifier with n, for example, ['n123', 'n456', ... ].

The comment author must have access to the attached files; otherwise, the method will return an error.

The field is completely overwritten. To add a file to already uploaded ones, pass the identifiers of all files in the array—both old and new.
