description: Connect CowAgent to WeCom AI Bot (WebSocket long connection)
---

> Connect CowAgent via WeCom AI Bot, supporting both internal direct messages and group chats. No public IP required — uses a WebSocket long connection, with Markdown rendering and streaming output.

<Note>
  WeCom Bot and WeCom App are two different integration methods. WeCom Bot uses a WebSocket long connection and requires no public IP or domain, making setup much simpler.
</Note>

## 1. Connection methods

### Option A: One-click QR scan (recommended)

No need to create the bot ahead of time. Start CowAgent and open the Web console (local URL: http://127.0.0.1:9899/), go to the **Channels** tab, click **Connect Channel**, choose **WeCom Bot**, switch to **QR scan** mode, and scan the QR code with **WeCom** — bot creation and connection complete automatically.

<Note>
  After a successful scan, you can further configure the bot (name, avatar, visibility scope, etc.) in **WeCom Workbench → AI Bot**.
</Note>

### Option B: Manual creation

Create the AI Bot in WeCom and obtain the Bot ID and Secret, then connect via the Web console or config file.

**Step 1: Create the AI Bot**

1. Open the WeCom client, go to **Workbench**, and click **AI Bot**:

4. Set the bot name, avatar, and visibility scope. Choose **Long Connection** mode, save the **Bot ID** and **Secret**, then click Save.

**Step 2: Connect to CowAgent**

<Tabs>
  <Tab title="Web Console">
    Open the Web console, go to the **Channels** tab, click **Connect Channel**, choose **WeCom Bot**, switch to **Manual** mode, enter the Bot ID and Secret, and click Connect.

    <img src="https://cdn.link-ai.tech/doc/20260316181711.png" width="800"/>
  </Tab>
  <Tab title="Config File">
    Add the following to `config.json`, then start CowAgent:

    ```json
    {
      "channel_type": "wecom_bot",
      "wecom_bot_id": "YOUR_BOT_ID",
      "wecom_bot_secret": "YOUR_SECRET"
    }
    ```

    | Parameter | Description |
    | --- | --- |
    | `wecom_bot_id` | Bot ID of the AI Bot |
    | `wecom_bot_secret` | Secret of the AI Bot |
  </Tab>
</Tabs>

The log line `[WecomBot] Subscribe success` confirms the connection is established.

<Note>
  A **webhook (HTTP callback) mode** is also supported: when creating the bot, choose **Use URL callback**, set the receive-message URL to `http(s)://<your-domain-or-ip>:9892/wecombot`, and copy the Token and EncodingAESKey from that page. This mode needs a publicly reachable address and does not support file sending or scheduled push, so the long connection is generally recommended. The corresponding `config.json`:

```json
{
  "channel_type": "wecom_bot",
  "wecom_bot_mode": "webhook",
  "wecom_bot_token": "YOUR_TOKEN",
  "wecom_bot_encoding_aes_key": "YOUR_ENCODING_AES_KEY",
  "wecom_bot_port": 9892
}
```
</Note>
