Remove from the saved list of blocks `landing.landing.unFavoriteBlock`

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: user with "edit" access permission for the site

The method landing.landing.unFavoriteBlock removes the saved copy of a block. The original block on the page remains unchanged. When a saved block is deleted, any associated files, such as a user-uploaded preview for that block, are also removed.

You can only delete a saved block that the current user created using the method landing.landing.favoriteBlock.

Method Parameters

Description

blockId*
integer

Identifier of the saved copy of the block.

The identifier can be obtained from the result of the method landing.landing.favoriteBlock.

If you pass the identifier of a regular block on the page or a non-existent identifier, the method will return an error
