Green API account at [green-api.com](https://green-api.com) 2. Instance created and authorized (QR code scanned) 3. Credentials configured in `.env` file ## Setup ### 1. Install Dependencies ```bash cd /home/user/architect-workshops/.claude/skills/whatsapp-group-info/scripts npm install ``` ### 2. Configure Credentials Copy `.env.example` to `.env` and fill in your credentials: ```bash cp .env.example .env ``` Edit `.env`: ``` GREEN_API_INSTANCE_ID=your_instance_id GREEN_API_TOKEN=your_api_token ``` Get these from [green-api.com console](https://console.green-api.com/). ## Usage ### Get Group Info ```bash cd /home/user/architect-workshops/.claude/skills/whatsapp-group-info/scripts npx ts-node get_group_info.ts "GROUP_ID" ``` **GROUP_ID format:** `120363123456789012@g.us` ### Example ```bash npx ts-node get_group_info.ts "120363044291817037@g.us" ``` ### Output Returns JSON with: - `groupId` - Group ID - `subject` - Group name - `size` - Number of participants - `participants` - Array of member details - `owner` - Group owner ID - `creation` - Creation timestamp ## Workflow ### 1. Find Group ID The Group ID should be stored in the workshop's `workshop.md` file under WhatsApp Group section. ### 2. Run the Script ```bash npx ts-node get_group_info.ts "GROUP_ID_FROM_WORKSHOP" ``` ### 3. Update Workshop Attendance After getting the group size, update the workshop's attendance table: ```markdown **Attendance:** | Metric | Count | |--------|-------| | WhatsApp Group Size | 45 | <-- Update this ``` ## Integration with Workshop Updates When user says "check group size for workshop X": 1.
