Create a Session-Based Telegram Chatbot with GPT-4o-mini and Google Sheets

n8n template #3798

Summary

How It Works This workflow creates an AI-powered Telegram chatbot with session management, allowing users to: Start new conversations (/new). Check current sessions (/current). Resume past sessions (/resume). Get summaries (/summary). Ask questions (/question). Key Components: Session Management: Uses Google Sheets to track active/expired sessions (storing SESSION IDs and STATE). /new creates a session; /resume reactivates past ones. AI Processing: OpenAI GPT-4 generates responses with contextual memory (via Simple Memory node). Summarization: Condenses past conversations when requested. Data Logging: All interactions (prompts/responses) are saved to Google Sheets for audit and retrieval. Us

How to set it up

Open template #3798 on n8n.io and click Use for free, or copy the template JSON and paste it onto an empty canvas in n8n.
Create 3 credentials under Credentials → Add credential: Google Sheets, Telegram, OpenAI Chat Model. Then open each of those nodes and pick the credential.
Check the model in the AI Agent node. The template may point at a model your account can't use; swap it for one you have access to.
Click Execute workflow and step through each node's output to confirm the data looks right.
Toggle the workflow to Active so its trigger runs on its own.
