Add site landing.site.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: landing

Who can execute the method: a user with "create" access permission for sites

The method landing.site.add creates a new site and returns the identifier of the created site.

Method Parameters

Required parameters are marked with *

Name `type`	Description
scope `string`	Internal scope of landings. It is not related to the REST scope `landing` in the method name. For `GROUP`, `KNOWLEDGE`, and `MAINPAGE`, the value of `scope` must match the value of `fields.TYPE` (detailed description)
fields* `object`	Set of fields for the new site (detailed description)

Parameter fields

Required parameters are marked with *

Name `type`	Description
TITLE* `string`	Title of the site, up to `255` characters
CODE* `string`	Symbolic code of the site. If an empty string is passed, the code will be generated from the `TITLE` field. For codes that consist only of digits, a prefix `site` will be automatically added. If such a value already exists in the domain, a numeric suffix will be added, for example, `code2` or `code3`
TYPE `string`	Type of the site. Default is `PAGE`. Supported types are `PAGE`, `STORE`, `SMN`, `KNOWLEDGE`, `GROUP`, `MAINPAGE`. The value must correspond to the `scope` parameter (detailed description)
DOMAIN_ID `integer` \| `string`	Domain of the site. The value depends on the platform. For Bitrix24, specify the domain name of the site. If the parameter is not filled or an empty string is passed, the domain will be generated automatically based on the system template. For 1C-Bitrix: Site Management, you need to pass the identifier of an already existing domain. Domain name as a string is not supported, the method will return an error
DESCRIPTION `string`	Description of the site, up to `255` characters
XML_ID `string`	External identifier, up to `255` characters
ADDITIONAL_FIELDS `object`	Additional fields of the site, stored separately after creation

Correspondence between TYPE and scope

Site types and rules for selecting the scope parameter are described in the article Working with site types and scopes.

fields.TYPE	scope in request	When to use
`PAGE`, `STORE`, `SMN`	do not pass	Site or store when the `scope` parameter is not passed
`GROUP`	`GROUP`	Group site
`KNOWLEDGE`	`KNOWLEDGE`	Knowledge base
`MAINPAGE`	`MAINPAGE`	Main page or vibe
