# WeCom (Enterprise WeChat)
Connect Hermes to [WeCom](https://work.weixin.qq.com/) (企业微信), Tencent's enterprise messaging platform. The adapter uses WeCom's AI Bot WebSocket gateway for real-time bidirectional communication — no public endpoint or webhook needed.
## Prerequisites
- A WeCom organization account
- An AI Bot created in the WeCom Admin Console
- The Bot ID and Secret from the bot's credentials page
## Setup
### 1. Create an AI Bot
1. Log in to the [WeCom Admin Console](https://work.weixin.qq.com/wework_admin/frame)
2. Navigate to **Applications****Create Application****AI Bot**
3. Configure the bot name and description
4. Copy the **Bot ID** and **Secret** from the credentials page
### 2. Configure Hermes
Run the interactive setup:
```bash
hermes gateway setup
```
Select **WeCom** and enter your Bot ID and Secret.
Or set environment variables in `~/.hermes/.env`:
```bash
WECOM_BOT_ID=your-bot-id
WECOM_SECRET=your-secret
# Optional: restrict access
WECOM_ALLOWED_USERS=user_id_1,user_id_2
# Optional: home channel for cron/notifications
WECOM_HOME_CHANNEL=chat_id
```
### 3. Start the gateway
```bash
hermes gateway start
```
## Features
- **WebSocket transport** — persistent connection, no public endpoint needed
- **DM and group messaging** — configurable access policies
- **Media support** — images, files, voice, video upload and download
- **AES-encrypted media** — automatic decryption for inbound attachments
- **Quote context** — preserves reply threading
- **Markdown rendering** — rich text responses
- **Auto-reconnect** — exponential backoff on connection drops
## Configuration Options
Set these in `config.yaml` under `platforms.wecom.extra`:
| Key | Default | Description |
|-----|---------|-------------|
| `bot_id` | — | WeCom AI Bot ID (required) |
| `secret` | — | WeCom AI Bot Secret (required) |
| `websocket_url` | `wss://openws.work.weixin.qq.com` | WebSocket gateway URL |
| `dm_policy` | `open` | DM access: `open`, `allowlist`, `disabled`, `pairing` |
| `group_policy` | `open` | Group access: `open`, `allowlist`, `disabled` |
| `allow_from` | `[]` | User IDs allowed for DMs (when dm_policy=allowlist) |
| `group_allow_from` | `[]` | Group IDs allowed (when group_policy=allowlist) |
## Troubleshooting
| Problem | Fix |
|---------|-----|
| "WECOM_BOT_ID and WECOM_SECRET are required" | Set both env vars or configure in setup wizard |
| "invalid secret (errcode=40013)" | Verify the secret matches your bot's credentials |
| "Timed out waiting for subscribe acknowledgement" | Check network connectivity to `openws.work.weixin.qq.com` |
| Bot doesn't respond in groups | Check `group_policy` setting and group allowlist |
