Setting up automatic crossposting with n8n

n8n is a powerful open-source automation platform that allows you to create complex workflows without programming. To set up crossposting from Telegram to VK, you need to follow several steps.

Environment Preparation

1. Register on n8n.cloud or install the local version
2. Create a Telegram bot through @BotFather to get the API token
3. Get the VKontakte group ID through the API method or special tools

Important: To work with VK API, you need to create an application in VK Developers and get an access key.

Creating Workflow

The main workflow includes the following steps:

// Example code for n8n Code node
const telegram = await this.helpers.request({
  url: `https://api.telegram.org/bot${telegramToken}/getUpdates`,
  method: 'GET'
});

const vkPost = await this.helpers.request({
  url: 'https://api.vk.com/method/wall.post',
  method: 'POST',
  headers: {
    'Content-Type': 'application/json'
  },
  body: {
    access_token: vkToken,
    v: '5.199',
    owner_id: vkGroupId,
    message: telegram.result[0].message.text,
    from_group: 1
  }
});

Setting up Triggers

To automatically track new messages, use:

• Webhook for Telegram (preferred method)
• Constant polling (polling) with an interval of 30-60 seconds

Using ready-made free bots

There are ready-made solutions that don’t require setup but have limitations.

Zen Bot

A bot for crossposting from Telegram to Zen can also be adapted to work with VK:

• Advantages: Easy setup, no technical knowledge required
• Limitations: Only works with public channels, may be paid

Alternative Free Bots

1. Telegram to VK Bot - a bot with a simple interface
2. AutoPoster Bot - supports multiple platforms
3. CrossPoster - specialized service for crossposting

Attention: Free versions of bots often have limitations on the number of posts per day or contain advertisements.

Alternative free solutions

Python scripts using libraries

For technically savvy users, you can create a Python script:

import telethon
import vk_api
from telethon.sync import TelegramClient
from vk_api.bot_longpoll import VkBotLongPoll, VkBotEventType

# Telegram setup
telegram_client = TelegramClient('session_name', api_id, api_hash)

# VK setup
vk_session = vk_api.VkApi(token=vk_token)
vk = vk_session.get_api()

GitHub Projects

On GitHub, you can find ready-made solutions:

• Telegram-to-VK-Bot - repository with open source code
• AutoCrossPoster - project with support for multiple platforms

Technical requirements and limitations

System Requirements

• n8n: Minimum 2GB RAM, stable internet connection
• Bots: No special requirements, works in browser

Limitations of Free Solutions

1. Number of posts: Usually 10-50 posts per day
