Update the documentgenerator.numerator.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: documentgenerator

Who can execute the method: a user with permission to modify document generator templates

The method documentgenerator.numerator.update updates the numerator by its identifier.

You can only update a numerator that was created through the REST method documentgenerator.numerator.add.

Method Parameters

Required parameters are marked with *

Name
type

Description

id*
integer

Identifier of the numerator.

You can obtain the identifier after creating a numerator or by using the method to get the list of numerators

fields*
object

Set of fields to update (detailed description)

Parameter fields

Name `type`	Description
name `string`	New name of the numerator
template `string`	New number template with the placeholder `{NUMBER}`. `{NUMBER}` should be specified in curly braces; when generating a document, the placeholder is replaced with the next counter value according to the `settings`. Template examples: `{NUMBER}` → `1000` `INV-{NUMBER}` → `INV-1000` `DG/{NUMBER}/2026` → `DG/1000/2026`
settings `object`	Updated generator settings (detailed description)

Parameter settings

Name `type`	Description
Bitrix_Main_Numerator_Generator_SequentNumberGenerator `object`	Settings for sequential numbering (detailed description)

Parameters Bitrix_Main_Numerator_Generator_SequentNumberGenerator

Name `type`	Description
start `integer`	Initial counter value. Default is `1`
step `integer`	Counter increment step. Default is `1`
length `integer`	Minimum length of the number. Default is `0`
padString `string`	Padding character on the left when `length > 0`. Default is `0`
periodicBy `string`	Counter reset period: `''` — no reset `day` — daily `month` — monthly `year` — yearly
timezone `string`	Timezone identifier for periodic reset, e.g., `Europe/Berlin`
isDirectNumeration `boolean`	Direct numbering flag. Possible values: `0` — disabled `1` — enabled Default is `0`. In the method response, the value is returned as `true`	`false`

Code Examples

How to Use Examples in Documentation
