"content": "# \ud83e\udd16 Telegram + Gemini + Google Docs Automation in n8n\n\n## \ud83d\udccc Overview\n\nThis n8n workflow listens for messages sent to a Telegram bot and replies with AI-generated responses using **Google Gemini (PaLM)**. It optionally interacts with **Google Docs** to fetch documents and makes external API requests using an **HTTP Request** node.\n\nThe flow also includes batching and waiting logic to control the pace of replies, making it scalable and human-friendly.\n\n---\n\n## \ud83e\udde0 What This Workflow Does\n\n### \u2705 1. Trigger from Telegram\n- **Node**: `Telegram Trigger`\n- **Function**: Starts the workflow when a message is received via your Telegram bot.\n\n### \u2705 2. Loop Through Messages\n- **Node**: `Loop Over Items`\n- **Function**: Allows processing multiple incoming messages if required, using batching logic.\n\n### \u2705 3. AI-Powered Reply with Gemini\n- **Node**: `Message a model` (Google Gemini Pro)\n- **Function**: Sends the message to the Gemini AI (via Google PaLM API) to generate a human-friendly, conversational response.\n\n### \u2705 4. Send AI Response via Telegram\n- **Node**: `Send a text message`\n- **Function**: Sends the generated Gemini response back to the user on Telegram.\n\n### \u2705 5. Delay Between Replies\n- **Node**: `Wait 1s`\n- **Function**: Adds a 1-second delay before proceeding to the next message in the loop (helps avoid Telegram rate limits and creates more natural pacing).\n\n### \u2705 6. Optional: External API Request\n- **Node**: `HTTP Request`\n- **Function**: Makes an external API request to `https://devcodejourney.com/` (placeholder URL).\n- **Note**: Currently not connected to message flow but can be used to fetch or send additional data.\n\n### \u2705 7. Optional: Fetch Document from Google Docs\n- **Node**: `Get a document in Google Docs`\n- **Function**: Retrieves the contents of a Google Docs document from a provided link. Can be used to add static text, FAQs, or templates to the conversation.\n\n### \u2705 8. Optional: Alternate Gemini Tool\n- **Node**: `Message a model in Google Gemini`\n- **Function**: Uses a different version (`gemini-2.0-flash-exp`) of the Gemini AI model for fast responses or testing purposes.\n\n---\n\n## \ud83d\udd27 Technologies Used\n\n- **Telegram Bot API** \u2013 for message triggers and replies \n- **Google Gemini (PaLM API)** \u2013 for AI-generated responses \n- **Google Docs API** \u2013 to fetch document content \n- **HTTP Request** \u2013 to connect to any third-party API \n- **n8n** \u2013 no-code/low-code workflow automation platform \n\n---\n\n## \u2699\ufe0f Use Cases\n\n- AI Chatbot for Telegram using Gemini \n- Personal Assistant or FAQ bot reading from Google Docs \n- Customer service bot that replies in natural language \n- Looping conversations with controlled pacing \n- External data fetching with AI processing \n\n---\n\n## \ud83d\udccc Notes\n\n- Make sure you have the correct credentials configured in n8n for:\n - Telegram Bot\n - Google Docs OAuth2\n - Google Gemini API (PaLM)\n- You can add error-handling nodes or conditionals to expand the logic.\n- This can be extended into a full AI chatbot or customer support bot.\n\n---\n\n## \ud83e\udde9 Nodes Used\n\n| Node Name | Type | Purpose |\n|-----------------------------------|----------------------------|-----------------------------------------|\n| Telegram Trigger | telegramTrigger | Listens for incoming Telegram messages |\n| Loop Over Items | splitInBatches | Handles batching of incoming data |\n| Message a model | langchain.googleGemini | Sends prompt to Google Gemini (Pro) |\n| Send a text message | telegram | Sends response back to Telegram user |\n| Wait 1s | wait | Adds a delay between responses |\n| HTTP Request | httpRequestTool | Sends HTTP request to external API |\n| Get a document in Google Docs | googleDocsTool | Fetches content from Google Docs |\n| Message a model in Google Gemini | googleGeminiTool | Alternate Gemini model for responses |\n\n---\n\n\n## \ud83d\ude4b For Help & Community\n- \ud83d\udc7e Discord: [n8n channel](https://discord.gg/9SDFKGnh2Y)\n- \ud83c\udf10 Website: [devcodejourney.com](https://devcodejourney.com)\n- \ud83d\udd17 LinkedIn: [Connect with Shakil](https://www.linkedin.com/in/shakilpg/)\n- \ud83d\udcf1 WhatsApp Channel: [Join Now](https://whatsapp.com/channel/0029Vb5l6JuDTkK5BRORNn0B)\n- \ud83d\udcac Direct Chat: [Message Now](https://wa.me/8801316320957)"
