Subscribe to Events im.v2.Event.subscribe

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: im

Who can execute the method: authorized user

The method im.v2.Event.subscribe subscribes the current user to event logging. After subscribing, message events are recorded in the log and become accessible through im.v2.Event.get.

The method is idempotent: repeated calls are safe and do not result in an error.

Method Parameters

The method does not accept any parameters.
