## Setup

1. Log in to the [WeCom Admin Console](https://work.weixin.qq.com/)
2. Go to "App Management" -> "Create App"
3. Obtain the Enterprise ID (CorpID) and App Secret
4. Configure "Receive Messages" in the app settings to get the Token and EncodingAESKey
5. Set the callback URL to `http://<your-server-ip>:<port>/webhook/wecom-app`
6. Enter the CorpID, Secret, AgentID, and other details into the config file

   Note: PicoClaw now uses a shared Gateway HTTP server to receive webhook callbacks for all channels. The default listening address is 127.0.0.1:18790. To receive callbacks from the public internet, reverse-proxy your external domain to the Gateway (default port 18790).
