GPT-4 Telegram support bot for e-commerce store

Task: replace a live support operator — bot answers customer
questions 24/7 based on FAQ and product catalog.

What was built:
— OpenAI GPT-4o API with store-specific system prompt
— RAG approach: bot searches FAQ base before generating response
— Unknown queries → escalation to live operator in thread
— Session memory: last 5 messages kept as context
— All conversations logged to Google Sheets
