description: Integrate CowAgent with Telegram via the Bot API
---

> Integrate CowAgent into Telegram via the official Bot API. Supports private chat and group chat (triggered by @mention or replying to the bot). Uses Long Polling — no public IP required, works out of the box.


## 1. Setup

### Step 1: Create a Bot via BotFather

1. Open the official account [@BotFather](https://t.me/BotFather) in Telegram.
2. Send `/newbot` and follow the prompts:
   - **Bot name** (display name, e.g. `My CowAgent Bot`)
   - **Bot username** (must end with `bot`, e.g. `my_cowagent_bot`)
3. Once created, BotFather returns an **HTTP API Token** (e.g. `123456789:ABCdefGhIJKlmNoPQRsTUVwxyZ`). Keep it safe.

<Tip>
  The token is the password of your bot — never share it. If it leaks, send `/revoke` to `@BotFather` to reset it.
</Tip>

### Step 2: (Group chat only) Disable Privacy Mode

Skip this step if you only use private chat. Telegram bots run in **Privacy Mode** by default — in groups they can only see commands suffixed with `@bot` (e.g. `/start@your_bot`) and replies to bot messages; **plain `@bot hello` text messages are not delivered**, so the bot will appear unresponsive in groups.

Send the following to `@BotFather`:

1. `/setprivacy`
2. Pick the bot you just created
3. Choose `Disable`

<Note>
  If the bot is still silent in groups after this, try removing it from the group and adding it back.
</Note>

### Step 3: Connect to CowAgent

<Tabs>
  <Tab title="Web Console (Recommended)">
    Open the Web Console (default `http://127.0.0.1:9899`), go to **Channels**, click **Add Channel**, choose **Telegram**, paste the Bot Token, and click connect.
  </Tab>
  <Tab title="Config File">
    Add the following to `config.json` and start Cow:

    ```json
    {
      "channel_type": "telegram",
      "telegram_token": "123456789:ABCdefGhIJKlmNoPQRsTUVwxyZ",
      "telegram_group_trigger": "mention_or_reply"
    }
    ```

    | Key | Description | Default |
    | --- | --- | --- |
    | `telegram_token` | HTTP API Token returned by BotFather | - |
    | `telegram_group_trigger` | Group trigger: `mention_or_reply` (@ or reply) / `mention_only` (@ only) / `all` (all messages) | `mention_or_reply` |
    | `telegram_register_commands` | Whether to register the command menu with BotFather on startup | `true` |
  </Tab>
</Tabs>

The integration is ready when you see logs like:

```
[Telegram] Bot logged in as @my_cowagent_bot (id=123456789)
[Telegram] Registered 10 bot commands
[Telegram] ✅ Telegram bot ready, polling for updates
```

## 2. Capabilities

| Feature | Support |

| Group chat (@bot / reply to bot) | ✅ |
| Text messages | ✅ send / receive |

### Command Menu

On startup, the channel registers a command menu with BotFather. Typing `/` in Telegram shows a dropdown:

| --- | --- |
| `/help` | Show command help |
| `/status` | View runtime status |
| `/context` | View conversation context (`/context clear` to clear) |

| `/config` | View current config |
| `/cancel` | Cancel the running Agent task |
| `/logs` | View recent logs |
| `/version` | Show version |

<Note>
  Telegram's command menu only displays top-level commands; subcommands are entered with a space, e.g. `/skill list`, `/context clear`.
</Note>

## 3. Usage

Once connected:

- **Private chat**: search for your bot username (e.g. `@my_cowagent_bot`) in Telegram, click `Start` and chat away.
- **Group chat**: add the bot to a group, then trigger it with `@bot hello` or by **replying to one of the bot's messages**. If the bot doesn't respond in groups, double-check Privacy Mode in [Step 2](#step-2-group-chat-only-disable-privacy-mode).

When sending an image or file, you can **add a caption** (description / question) directly in the attachment input — the bot will answer based on both. Sending an attachment first and then a follow-up question also works; the two messages are merged automatically.
