Migration from imbot to imbot.v2

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.

A mapping table of methods and events between the deprecated API (imbot) and the new bot platform (imbot.v2).

Methods v1 and v2 operate in parallel. Bots registered through v1 are visible in v2 and vice versa. However, the event formats differ — the bot receives events only in the format of the API version through which it was registered.

  • Nested objects instead of flat fields — Bot, Chat, Message, User
  • Boolean fields — actual true/false instead of strings "Y"/"N"

Event Delivery

  • v1: only webhook (EVENT_HANDLER URL)
  • v2: fetch mode (polling via imbot.v2.Event.get) + webhook mode as an option when registering the bot

Method Parameters

  • v1: flat top-level parameters (MESSAGE_ADD, BOT_ID, TYPE, etc.)
  • v2: grouping in fields.* / properties.*, camelCase names

Authorization

  • v1: OAuth or webhook authorization with CLIENT_ID field
  • v2: OAuth or webhook authorization with botToken

Changes within v2

The API imbot.v2 continues to evolve. New features, fixes, and changes with loss of backward compatibility are published in the API imbot.v2 Change Log.

If the format of a method's call or response changes, the previous version will continue to be supported for 6 months from the date of the change publication.
