Connecting and Using BX24.js
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.
If your application implements a user interface within Bitrix24 (displayed on a special page or using embedding tools), you can take advantage of the capabilities of a special JS library. It:
- first, serves as a JS SDK for REST, allowing you to access REST directly from the front-end of your application without delving into authorization implementation via OAuth 2.0,
- second, offers a range of additional features for interacting your application's user interface with the Bitrix24 interface:
- frame size management,
- calling standard dialogs,
- etc.
The library is connected as follows:
<script src="//api.bitrix24.com/api/v1/"></script>
The library cannot be used for external applications and webhooks.
