It automates two main processes:\n1.  **Creating a new Google Calendar event** from a list provided in a Google Sheet.\n2.  **Using an AI Agent (Gemini/LLM)** to propose suitable follow-up meeting slots for recently completed calendar events.\n\n## ✨ Features\n* **Scheduled Automation:** Both event creation and follow-up scheduling run automatically on a recurring schedule.\n* **Data Synchronization:** Reads meeting details from, and updates the processed status in, a **Google Sheet**.\n* **Google Calendar Integration:** Creates events and checks calendar availability for follow-up suggestions.\n* **Multi-Channel Communication:** Sends confirmations and follow-up proposals via **WhatsApp (Rapiwa)** and **Email (Gmail)**.\n* **AI-Powered Follow-up:** An **AI Agent (Gemini)** intelligently finds and formats available slots for the next meeting, considering details like the past meeting's day, time, and duration.\n* **Idempotency:** The \"Mark as Seen\" node prevents duplicate follow-up attempts for the same event.\n\n## 🛠️ Requirements\n* An n8n instance (The workflow uses nodes like Schedule Trigger, Google Sheets, Google Calendar, Rapiwa, Gmail, Filter, Agent (LangChain), LLM Chat (Google Gemini), etc.).\n* **Google Calendar** with an available calendar for event creation and availability checks.\n* **Google Sheets** for storing meeting details.\n* **Rapiwa** (WhatsApp API) account credentials.\n* **Gmail** account credentials.\n* **Google Gemini (PaLM) API** credentials for the AI agent functionality.\n\n## 📊 Google Sheet Required Columns\nThe workflow expects a Google Sheet with meeting data to have at least the following columns:\n**A Google Sheet formatted like this** ➤ [Sample Sheet](https://docs.google.com/spreadsheets/d/1DSRrIDvw-Q9NugRK3eT7GMa0kwe0QnGhdySnqq1_kJU/edit?usp=sharing)\n\n\n## 🚀 How to Use This Workflow\n### Step 1: Setup Credentials\n* Set up your **Google Sheets OAuth2**, **Google Calendar OAuth2**, **Rapiwa API**, **Gmail OAuth2**, and **Google Gemini(PaLM) API** credentials in n8n.\n\n### Step 2: Configure the \"Create Event\" Branch\n* **Get in sheet:** Update the **Document ID** and **Sheet Name** to point to your meeting data spreadsheet.\n* **Create an event:** Verify the correct **Calendar ID** is selected.\n* **Rapiwa / Send a message1** and **Gmail:** Update the recipient number/email address and customize the message templates.\n* **Update status in sheet:** Ensure the correct **Document ID**, **Sheet Name**, and matching column (`row\\_number`) are configured to update the status to \"sent\".\n\n### Step 3: Configure the \"Reminder Event\" Branch\n* **Get Past Events:** Verify the correct **Calendar ID** is selected.\n* **Only Follow Ups:** Customize the filter condition if only a subset of past meetings needs follow-up.\n* **Meeting Agent:** Review the **System Message** to ensure the AI's logic for finding slots matches your business rules (e.g., preferred working hours, look-ahead period).\n* **Generate Message:** Customize the **message** template, which formats the AI-suggested slots.\n* **Rapiwa1 / Send a message** and **Gmail1:** Update the recipient number/email address for the follow-up messages.\n\n## ⚠️ Notes and Warnings\n* Ensure the **\"Mark as Seen\"** node is working correctly to prevent sending duplicate follow-up messages for the same event.\n* Validate that the column names in your Google Sheet **exactly match** the column names expected by the nodes in the workflow.\n* Thoroughly test the **System Message** for the AI Agent to confirm the output is formatted and prioritized according to your needs.\n\n## Useful Links\n- **Dashboard:** [https://app.rapiwa.com](https://app.rapiwa.com/login)\n- **Official Website:** [https://rapiwa.com](https://rapiwa.com/)\n- **Documentation:** [https://docs.rapiwa.com](https://docs.rapiwa.com/)\n\n## Support & Help\n- **WhatsApp**: [Chat on WhatsApp](https://wa.me/8801322827799)\n- **Discord**: [SpaGreen Community](https://discord.gg/SsCChWEP)\n- **Facebook Group**: [SpaGreen Support](https://www.facebook.com/groups/spagreenbd)\n- **Website**: [https://spagreen.net](https://spagreen.net)\n- **Developer Portfolio**: [Codecanyon SpaGreen](https://codecanyon.net/user/spagreen/portfolio)e me to focus on the **System Message** configuration for the **AI Meeting Agent** next?"
