Telegram FAQ Bot: Gemini + Google Sheets for n8n Automation

Answer Telegram FAQs instantly—using Google Gemini + your Google Sheets FAQ

This n8n automation workflow turns incoming Telegram messages into fast, accurate FAQ replies. It reads your questions and answers from Google Sheets, uses Google Gemini to respond in the customer’s language, logs every exchange, and alerts you when a human handoff is needed.

What this workflow does

When someone messages your Telegram bot, the workflow:

• Listens for incoming Telegram messages and starts a conversation for that chat.
• Loads your business details and reads the complete FAQ table from a Google Sheets “FAQ” tab (Question, Answer columns).
• Uses Google Gemini with 10-message chat memory per chat to generate a reply based strictly on your FAQ and business info, then sends it back via Telegram.
• Runs a second Gemini step to classify the exchange as “Answered” or “Needs a person”.
• Appends conversation details to the Google Sheets “Log” tab (Time, Customer, Message, Reply, Needs a person).
• If human help is required, alerts the owner on Telegram and logs the handoff in Sheets.

Use cases

• Reduce support load by answering common questions on Telegram using your existing FAQ.
• Handle multilingual customers by responding in the customer’s language with Gemini.
• Keep an audit trail of every FAQ attempt and immediately flag conversations that need escalation.
