Get Comment by ID task.commentitem.get
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:
taskWho can execute the method: any user with read access permission to the task or higher.
The method task.commentitem.get retrieves a comment by its ID.
DEPRECATED
Development of this method has been halted since version tasks 25.700.0. The method task.commentitem.get does not work in the new task card; use the im.dialog.messages.get method to work with task chat.
Method Parameters
Pass parameters in the request according to the order in the table. If the order is violated, the request will return an error.
Required parameters are marked with *
|
Name |
Description |
|
TASKID* |
Task ID. The task ID can be obtained when creating a new task or by using the get task list method. |
|
ITEMID* |
Comment ID. The comment ID can be obtained when adding a new comment or by using the get comment list method. |

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 |
Description |
|
|
|
An internal server error has occurred. Retry the call, and if the error persists, contact the server administrator or Bitrix24 technical support |
|
|
|
The server returned an unexpected response. Retry the call, and if the error persists, contact the server administrator or Bitrix24 technical support |
|
|
|
The request intensity limit has been exceeded |
|
|
|
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 |
|
|
|
The request contains no authorization data: neither an access token nor a webhook code was passed |
|
|
|
Methods are called over the HTTPS protocol only |
|
|
|
The REST API is blocked due to overload. This is a manual individual block. To have it lifted, contact Bitrix24 technical support |
|
|
|
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 — |
|
|
|
No active webhook with the specified user identifier and secret code was 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 |
|
|
|
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 |
|
|
|
The access token has expired |
|
|
|
The application is installed, but the Bitrix24 administrator has granted access to it only to specific users |
