Right Sidebar of the TASK_VIEW_SIDEBAR Card

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: task

You can add your item to the right sidebar of the old task card.

Since version tasks 25.700.0, a new task card has been released. The location for the TASK_VIEW_SIDEBAR item is absent in the new card. All integrations within the card are displayed in a single "Applications" block.

Previously registered TASK_VIEW_SIDEBAR items continue to function and are displayed in the "Applications" block.

Embedded applications

The specific placement code for the widget is specified in the PLACEMENT parameter of the placement.bind method.

The integration will not be displayed in the interface until the application installation is complete. Check the application installation
