Update Content of the Block landing.block.updatecontent

If you are developing integrations for Bitrix24 using AI tools (Codex, Claude Code, Cursor), connect the MCP server so that the assistant can utilize the official REST documentation.

Scope: landing

Who can execute the method: a user with "edit" access permission for the site

The method landing.block.updatecontent completely replaces the HTML content of a block in the page draft.

If you only need to change specific nodes, attributes, or styles of the block, use the methods landing.block.updatenodes, landing.block.updateattrs, and landing.block.updateStyles.

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. The value of `scope` must correspond to the type of site (detailed description)
lid* `integer`	Identifier of the page. The page identifier can be obtained using the method landing.landing.getList
block* `integer`	Identifier of the block in the page draft. The block identifier can be obtained using the method landing.block.getlist with the parameter `params.edit_mode = 1`. If you pass the block identifier from the published version of the page, the method may return an error
content* `string`	New HTML content of the block. The method completely replaces the current content of the block. The current HTML of the block can be obtained using the method landing.block.getcontent or the method landing.block.getlist with the parameter `params.get_content = true`
designed `boolean` \| `integer` \| `string`	Marks the block as manually modified. To enable this flag, pass `true`, `"true"`, or `1`. Any other value will not enable it. Default is `false`
preventHistory `boolean`	Do not add the change to the page history. Default is `false`
