🌟 Key Features

• Unified Messaging: Receive and normalize messages from both Telegram (via Bot Trigger) and WhatsApp (via Webhook).
• Contextual AI Responses: Build customer context from Google Sheets, then craft personalized replies with GPT-4 Turbo.
• Smart Routing: Automatically detect platform and send replies with platform-appropriate formatting (HTML for Telegram, plain for WhatsApp).
• Intent Detection & Escalation: Flag orders, appointments or complex queries and trigger Slack notifications for human handoff.
• Comprehensive Logging: Append every interaction to a “conversations” sheet and upsert customer profiles in a “customers” sheet.

4. Build AI Context: Merges incoming message with customer info and history.
5. AI Assistant: Sends context to GPT-4 Turbo (temperature 0.8, maxTokens 800).
6. Process Response: Cleans formatting, identifies intents (order, appointment), and sets escalation flags.
7. Platform Router: Routes reply to the appropriate “Send Telegram” or “Send WhatsApp” node.
8. Log Conversation: Appends each message and response to the “conversations” sheet.
9. Update Customer: Increments previousOrders, updates last interaction timestamp, and saves a snippet of the latest message.
10. Escalation: If flagged, posts a formatted alert to your Slack channel for immediate attention.
