Integrate CowAgent into Feishu by creating a custom enterprise app. You need to be a Feishu enterprise user with admin privileges.

## 1. Create Enterprise Custom App

### 1.1 Create App

Go to [Feishu Developer Platform](https://open.feishu.cn/app/), click **Create Enterprise Custom App**, fill in the required information and click **Create**:

### 1.2 Add Bot Capability

In **Add App Capabilities**, add **Bot** capability to the app:

### 1.3 Configure App Permissions

Click **Permission Management**, paste the following permission string into the input box below **Permission Configuration**, select all filtered permissions, click **Batch Enable** and confirm:

```
im:message,im:message.group_at_msg,im:message.group_at_msg:readonly,im:message.p2p_msg,im:message.p2p_msg:readonly,im:message:send_as_bot,im:resource,cardkit:card:write
```

`cardkit:card:write` is used for streaming typewriter replies (creating and updating streaming cards). You can skip it if streaming is not needed.

## 2. Project Configuration

1. Get `App ID` and `App Secret` from **Credentials & Basic Info**:

2. Add the following configuration to `config.json` in the project root:

```json
{
  "channel_type": "feishu",
  "feishu_app_id": "YOUR_APP_ID",
  "feishu_app_secret": "YOUR_APP_SECRET",
  "feishu_stream_reply": true
}
```

| Parameter | Description | Default |
| --- | --- | --- |
| `feishu_app_id` | Feishu bot App ID | - |
| `feishu_app_secret` | Feishu bot App Secret | - |
| `feishu_stream_reply` | Enable streaming typewriter reply (powered by Feishu cardkit streaming card API). Disable to return the full text at once. | `true` |

> **Streaming requirements**: requires `cardkit:card:write` permission on the bot, and recipient Feishu client version ≥ 7.20. Older clients will see a "please upgrade" placeholder; if the permission is missing, replies automatically fall back to plain text.

Start the project after configuration is complete.

## 3. Configure Event Subscription

1. After the project is running successfully, go to the Feishu Developer Platform, click **Events & Callbacks**, select **Long Connection** mode, and click save:

2. Click **Add Event** below, search for "Receive Message", select "**Receive Message v2.0**", and confirm.

3. Click **Version Management & Release**, create a new version and apply for **Production Release**. Check the approval message in the Feishu client and approve:
