Get API Revisions imbot.v2.Revision.get

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: imbot

Who can execute the method: any user

The method imbot.v2.Revision.get returns the revision numbers of the REST API and client protocols of the messenger. It is used to check compatibility: which methods and features are supported by a specific Bitrix24.

Purpose of the Method

Cloud and on-premise versions of Bitrix24 may have different API revisions. Cloud Bitrix24 instances are updated automatically, while on-premise installations may lag behind in capabilities.

By calling imbot.v2.Revision.get before using new methods or fields, the application can:

  • determine which features are available on the current Bitrix24
  • adapt the bot's logic to the API revision
  • correctly handle scenarios where the required functionality is not yet available to the client

In the method documentation, you may see the note “available from revision N”. This means that the field or behavior was introduced starting from the specified revision.

Method Parameters

The method does not require botId and botToken. There are no parameters.

How to Use

A typical scenario is to check before using a method or field that appeared in a specific revision:

const revision = await BX.rest.callMethod('imbot.v2.Revision.get', {});
        const restRevision = revision.data().rest;
        
        if (restRevision >= 33)
        {
            await BX.rest.callMethod('imbot.v2.Chat.Message.send', {
                botId: 456,
                botToken: '...',
                dialogId: 'chat5',
                fields: { message: 'Hello', system: true }
            });
        }
        else
        {
            // system may not work correctly in earlier revisions
        }
