Configure Webhook Chat Trigger\n**Node:** `When chat message received`\n- Connect your chat system (e.g., Telegram, Slack)\n- This node captures the user input message\n\n### 2. (Optional) Handle Google Docs Input\n\n**Node:** `Get a document in Google Docs`\n- If the user's message includes a link or ID of a Google Doc, this node retrieves and simplifies it\n- The LangChain Agent can call this automatically when it detects a document reference\n\n### 3. Generate AI Response\n\n**Node:** `Google Gemini Chat Model`\n- LangChain routes message through the Gemini model\n- It generates a smart, contextual response, optionally using tools (e.g., Docs reader)\n\n\n### 4. Log Conversation in Google Sheet\n\n**Node:** `Append row in sheet`\n- Automatically appends:\n- Timestamp\n- User's message\n- AI's response\n\n## 🙋 For Help & Community\n\n- 🌐 Website: [devcodejourney.com](https://devcodejourney.com)\n- 🔗 LinkedIn: [Connect with Shakil](https://www.linkedin.com/in/shakilpg/)\n- 📱 WhatsApp Channel: [Join Now](https://whatsapp.com/channel/0029Vb5l6JuDTkK5BRORNn0B)\n- 💬 Direct Chat: [Message Now](https://wa.me/8801316320957)\n\n\n> Happy Building with 🛠️ **n8n + Gemini + Google Sheets**! 🚀"},"typeVersion":1},{"id":"092b6a15-91e6-4ee9-8be7-fc45d3fd7d0c","name":"Gemini","type":"@n8n/n8n-nodes-langchain.googleGeminiTool","position":[144,272],"parameters":{"modelId":{"__rl":true,"mode":"list","value":"models/gemini-2.5-flash","cachedResultName":"models/gemini-2.5-flash"},"options":{},"messages":{"values":[{"role":"model","content":"Give me user user-friendly reply.
