Update Call List Composition crm.calllist.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: crm

Who can execute the method: user with read access permission for CRM entities

The crm.calllist.update method allows you to add or remove participants from an existing call list and update the associated CRM form.

Method Parameters

Required parameters are marked with *

Name `type`	Description
LIST_ID* `integer`	Identifier of the call list
ENTITY_TYPE* `string`	Type of entity: `CONTACT` — contact, `COMPANY` — company
ENTITIES* `array`	Array of `ID`s of contacts or companies, which can be obtained using the crm.item.list method
WEBFORM_ID `integer`	`ID` of the CRM form that will be displayed in the call form. The `ID` can be found in the list of forms in Bitrix24 https://your-domain.com/crm/webform/

Method Operation Features

The method overwrites the ENTITIES array. To add an element, include both current and new IDs in the request:

Current IDs: [1,2,3].
New IDs: [4].
Send: [1,2,3,4].

To remove an element, send only those IDs that should remain in the list:

Current IDs: [1,2,3].
Remove: [2].
Send: [1,3].

The method overwrites the WEBFORM_ID field. If the WEBFORM_ID field is not provided when calling the method, it will be cleared.
