Telegram

This guide covers setting up a Qwen Code channel on Telegram.

Prerequisites

  • A Telegram account
  • A Telegram bot token (see below)

Creating a Bot

  1. Open Telegram and search for @BotFather 
  2. Send /newbot and follow the prompts to choose a name and username
  3. BotFather will give you a bot token — save it securely

Finding Your User ID

To use senderPolicy: "allowlist" or "pairing", you need your Telegram user ID (a numeric ID, not your username).

The easiest way to find it:

  1. Search for @userinfobot  on Telegram
  2. Send it any message — it will reply with your user ID

Configuration

Add the channel to ~/.qwen/settings.json:

{
  "channels": {
    "my-telegram": {
      "type": "telegram",
      "token": "$TELEGRAM_BOT_TOKEN",
      "senderPolicy": "allowlist",
      "allowedUsers": ["YOUR_USER_ID"],
      "sessionScope": "user",
      "cwd": "/path/to/your/project",
      "instructions": "You are a concise coding assistant responding via Telegram. Keep responses short.",
      "groupPolicy": "disabled",
      "groups": {
        "*": { "requireMention": true }
      }
    }
  }
}

Set the bot token as an environment variable:

export TELEGRAM_BOT_TOKEN=<your-token-from-botfather>

Or add it to a .env file that gets sourced before running.

Running

# Start only the Telegram channel
qwen channel start my-telegram
 
# Or start all configured channels together
qwen channel start

Then open your bot in Telegram and send a message. You should see “Working…” appear immediately, followed by the agent’s response.

Group Chats

To use the bot in Telegram groups:

  1. Set groupPolicy to "allowlist" or "open" in your channel config
  2. Disable privacy mode in BotFather: /mybots → select your bot → Bot Settings → Group Privacy → Turn Off
  3. Add the bot to a group. If it was already in the group, remove and re-add it (Telegram caches privacy settings from when the bot joined)
  4. If using groupPolicy: "allowlist", add the group’s chat ID to groups in your config

By default, the bot requires an @mention or a reply to respond in groups. Set "requireMention": false for a specific group to make it respond to all messages (useful for dedicated task groups). See Group Chats for full details.

Images and Files

You can send photos and documents to the bot, not just text.

Photos: Send a photo and the agent will analyze it using its vision capabilities. This requires a multimodal model — add "model": "qwen3.5-plus" (or another vision-capable model) to your channel config. Photo captions are passed as the message text.

Documents: Send a PDF, code file, or any document. The bot downloads it and saves it locally so the agent can read it with its file tools. This works with any model. Telegram’s file size limit is 20MB.

Tips

  • Keep instructions concise-focused — Telegram has a 4096-character message limit. Adding instructions like “keep responses short” helps the agent stay within bounds.
  • Use sessionScope: "user" — This gives each user their own conversation. Use /clear to start fresh.
  • Restrict access — Use senderPolicy: "allowlist" for a fixed set of users, or "pairing" to let new users request access with a code you approve via CLI. See DM Pairing for details.

Message Formatting

The agent’s markdown responses are automatically converted to Telegram-compatible HTML. Code blocks, bold, italic, links, and lists are all supported.

Troubleshooting

Bot doesn’t respond

  • Check that the bot token is correct and the environment variable is set
  • Verify your user ID is in allowedUsers if using senderPolicy: "allowlist", or that you’ve been approved if using "pairing"
  • Check the terminal output for errors

Bot doesn’t respond in groups

  • Check that groupPolicy is set to "allowlist" or "open" (default is "disabled")
  • If using "allowlist", verify the group’s chat ID is in the groups config
  • Make sure Group Privacy is turned off in BotFather — without this, the bot can’t see non-command messages in groups
  • If you changed privacy mode after adding the bot to a group, remove and re-add the bot to the group
  • By default, the bot requires an @mention or a reply. Send @yourbotname hello to test

”Sorry, something went wrong processing your message”

This usually means the agent encountered an error. Check the terminal output for details.

Bot takes a long time to respond

The agent may be running multiple tool calls (reading files, searching, etc.). The “Working…” indicator shows while the agent is processing. Complex tasks can take a minute or more.
