Update Unit of Measurement v 3.0 catalog.measure.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: catalog

Who can execute the method: a user with permission to read the catalog or view warehouses and to modify measurement units

The method belongs to REST 3.0. The call specifics and response format of the new API version are described in the REST 3.0 overview.

The catalog.measure.update method updates a unit of measurement and returns its data after the update.

Method Parameters

Required parameters are marked with *

Name
type

Description

id*
integer

Unit of measurement identifier.

The identifier can be retrieved using the catalog.measure.list method or from the catalog.measure.add response

fields*
object

Object with the unit of measurement fields to update. Pass only the fields being changed. Field description

An empty object {} returns the unit data without changes

Parameter fields

Name
type

Description

code
integer

Unit of measurement code. The value must be unique: if another unit already uses the code, the method returns an error

measureTitle
string

Name of the unit of measurement

symbol
string

Symbol

symbolIntl
string

International symbol

symbolLetterIntl
string

International letter code symbol

isDefault
boolean

Default unit of measurement flag. The default unit is selected automatically in a new product form.

Possible values:

  • true — default unit
  • false — regular unit

There can be only one default unit, and the method does not clear the flag on the current unit automatically. To make another unit the default one, make two calls: pass false for the current unit, then true for the new one. You can find the current default unit using the catalog.measure.list method with the [["isDefault","=",true]] filter

How to Use Examples in Documentation

The new API call differs by adding the /api/ segment to the request URL:

This request requires data type int in field code

Pass the code as a number

isDefault

This request requires data type bool in field isDefault

Pass true or false, not Y or N

-

Duplicate entry for key [code]

Another unit already uses this code. Specify a different code

-

default value can be set once [isDefault]

First pass false in isDefault for the current default unit

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

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
