Register a New User Field Type userfieldtype.add

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: depending on the placement

Who can execute the method: any user

The method userfieldtype.add registers a new type of user fields. After registering the type, create a user field using the userfieldconfig.add method.

When opening a card with a user type field, an array PLACEMENT_OPTIONS containing data about the field and entity is passed to the application handler.

{
            "MODE": "view",
            "ENTITY_ID": "CRM_DEAL",
            "FIELD_NAME": "UF_CRM_TEST_TYPE_1",
            "ENTITY_VALUE_ID": "7303",
            "VALUE": null,
            "MULTIPLE": "N",
            "MANDATORY": "N",
            "XML_ID": null,
            "ENTITY_DATA": {
                "entityTypeId": 2,
                "entityId": "7303",
                "module": "crm"
            }
        }

Name `type`	Description	Restrictions
USER_TYPE_ID* `string`	String code of the type	a-z0-9 must be unique the final code is formed as `rest_<APP_ID>_<USER_TYPE_ID>` and cannot exceed 50 characters, so the length of `USER_TYPE_ID` must be no more than `50 - length("rest_<APP_ID>_")`
HANDLER* `URL`	Address of the user type handler	in the same domain as the main application address must be unique
TITLE `string`	Text title of the type. Will be displayed in the administrative interface for user field settings
