QQ Bot (QQ机器人)

This guide covers setting up a Qwen Code channel on QQ via the official QQ Bot Open Platform API.

Prerequisites

• A QQ account (mobile app for scanning the QR code)

Setup

QR Code Login

Start the channel — the first time it will show a QR code. Scan it with your QQ app to activate. No developer account or manual registration needed. Credentials are saved and reused automatically.

{
  "channels": {
    "my-qq": {
      "type": "qq"
    }
  }
}

qwen channel start my-qq
# Scan the QR code in the terminal with your QQ app

Manual Configuration (Developer Portal)

You can also use credentials from the QQ Bot Open Platform developer portal if you already have an app registered there:

{
  "channels": {
    "my-qq": {
      "type": "qq",
      "appID": "YOUR_APP_ID",
      "appSecret": "$QQ_APP_SECRET"
    }
  }
}

Set the secret as an environment variable:

export QQ_APP_SECRET=<your-app-secret>

Configuration

{
  "channels": {
    "my-qq": {
      "type": "qq",
      "appID": "YOUR_APP_ID",
      "appSecret": "$QQ_APP_SECRET",
      "sandbox": false,
      "senderPolicy": "open",
      "sessionScope": "user",
      "cwd": "/path/to/your/project",
      "instructions": "你是一个通过 QQ Bot 对话的 AI 助手。回复控制在 2000 字符以内。",
      "blockStreaming": "on",
      "groupPolicy": "disabled",
      "groups": {
        "*": { "requireMention": true }
      }
    }
  }
}

QQ-Specific Options

All standard channel options (see Channel Overview) are also supported: senderPolicy, allowedUsers, sessionScope, cwd, instructions, groupPolicy, groups, dispatchMode, blockStreaming, blockStreamingChunk, blockStreamingCoalesce.

Running

# Start only the QQ channel
qwen channel start my-qq

# Or start all configured channels together
qwen channel start

Open QQ and send a message to your bot. You should see the response arrive in your chat.

Group Chats

To use the bot in QQ groups:

1. Set groupPolicy to "allowlist" or "open" in your channel config
2. Add the bot to a QQ group via the QQ Bot Open Platform dashboard or by having a group admin invite it
3. Group members must @mention the bot to trigger a response

QQ Bot API V2 only delivers group messages that @mention the bot — the bot does not see all group messages. By default, requireMention is true and should be left that way for QQ.

See Group Chats for full details on group policies and mention gating.

Markdown Support

The QQ Bot channel supports Markdown formatting (msg_type=2). The agent's Markdown responses are sent as-is, and QQ renders them with rich formatting (bold, italic, code blocks, links, lists).

If the QQ server rejects a Markdown message for any reason, the channel automatically retries it as plain text — so your messages always go through even if the bot's Markdown capability is restricted server-side.

This is the opposite of the WeChat channel, which strips all Markdown. You can let the agent use full Markdown with the QQ channel.

Token Management

Access tokens expire after approximately 2 hours. The channel automatically refreshes them at 80% of their TTL (typically ~1.6 hours). If a refresh fails, it retries after 60 seconds.

Token refresh continues across WebSocket reconnects — the channel never goes offline due to an expired token as long as the AppID and AppSecret remain valid.

Connection Resilience

• Auto-reconnect: On WebSocket disconnect, the channel retries with exponential backoff (up to 20 attempts, max 30 seconds between retries)
• Session resume: If the WebSocket drops briefly, the channel uses QQ's RESUME opcode to restore the session without losing in-flight messages
• Cross-server context continuation: Chat sessions and routing state are persisted to disk. If the daemon restarts, conversations continue from where they left off
• Heartbeat monitoring: HEARTBEAT_ACK timeouts are detected and force a reconnection to avoid zombie connections
• Message deduplication: Replayed messages after a reconnect are detected and skipped

Tips

• Use Markdown freely — Unlike WeChat, QQ renders Markdown natively. Bold, code blocks, lists, and links all work.
• Keep responses under 2000 characters — Longer responses are automatically split into chunks. Adding a length hint to your instructions helps the agent stay concise.
• Sandbox for testing — Set "sandbox": true to use the sandbox API during development. No production messages will be affected.
• Restrict access — Use senderPolicy: "allowlist" for a fixed set of QQ users, or "pairing" to approve new users from the CLI. See DM Pairing for details.

Key Differences from Telegram

Troubleshooting

Bot doesn't respond

• Check the terminal output for errors
• Verify the channel is running (qwen channel status)
• If using senderPolicy: "allowlist", make sure your QQ user ID is in allowedUsers
• On first start, a QR code will appear in the terminal — scan it with your QQ app

Bot doesn't respond in groups

• Check that groupPolicy is set to "allowlist" or "open" (default is "disabled")
• You must @mention the bot — QQ only delivers messages that tag the bot
• Verify the bot has been added to the group

QR code login is stuck

• The QR code is displayed in the terminal. Scan it with your QQ mobile app (Me → Scan)
• If the QR code expires (typically after a few minutes), restart the channel to get a new one

Markdown messages appear as plain text

• The QQ server may have rejected the Markdown message and the channel silently fell back to plain text. Check the terminal for "Markdown rejected" log messages
• This is unusual on the QQ Bot Open Platform but can happen if the bot's Markdown capability is restricted server-side

Token expired after long downtime

• If the channel is offline for more than 2 hours, the access token will have expired. The channel fetches a fresh token on reconnect — no action needed
• If the AppSecret itself is invalid (e.g., rotated in the developer portal), update the appSecret field or delete ~/.qwen/channels/<name>-credentials.json to re-trigger QR code login
