It parses customer messages, logs orders, and schedules fulfillment.\n\n### 🧾 What it does\n- Listens to incoming customer messages on Facebook Messenger.\n- Sends greeting + order form.\n- Uses AI to parse customer responses.\n- Saves details to Google Sheets.\n- Creates calendar events for delivery/pickup.\n- Sends confirmation + upsell message.\n\n### 🛠 Requirements\n- **Facebook Page** + Page Access Token from Meta.\n- **Google Sheets** with columns: `Date`, `Time`, `Order`, `Full Name`, `Contact Number`, `Delivery Address`.\n- **Google Calendar** for scheduling.\n- **n8n instance** (self-hosted or cloud).\n\n### 🔑 Environment variables (place these as n8n credentials or env vars)\n| Variable | Purpose | Example |\n|---|---:|---|\n| `FB_PAGE_ID` | Facebook Page ID | `123456789` |\n| `FB_PAGE_ACCESS_TOKEN` | Long-lived Page token | `EAAG...` |\n| `FB_VERIFY_TOKEN` | For webhook validation | `random-string` |\n| `YOUR_GOOGLE_SHEET_ID` | Google Sheet document ID | `1AbCdEfG...` |\n| `YOUR_SHEET_GID_OR_NAME` | Sheet name or GID | `Sheet1` |\n| `YOUR_GOOGLE_CALENDAR_EMAIL` | Calendar where events are added | `you@email.com` |\n\n### ⚠️ Troubleshooting\n- **Webhook not triggering?** Ensure Facebook App is in Live Mode, webhook URL is reachable, and the verify token matches.\n- **No Sheet rows after import?** Share the sheet with the connected Google account and verify headers match exactly.\n- **AI not parsing orders?** Check the OpenRouter model credentials and that model name is valid. Also test with simple messages.\n- **403 / permission errors?** Confirm tokens and credentials are correctly set in n8n Credentials, not in node JSON.\n\n---\n✅ **Next steps:** Clone this workflow, connect credentials, add a screenshot/loom video (recommended), then resubmit to n8n.\n"
