Multi-Department Telegram Support Bot with Slash Commands & Pinecone

This n8n workflow powers a sophisticated Telegram chatbot designed for multi-department customer support. Users interact via intuitive slash commands like /billing for payments, /tech-support for technical issues, and /return-policy for refunds, enabling instant routing to the appropriate support team or knowledge base. The core logic uses a Switch node to parse incoming messages and direct them to specialized paths, ensuring efficient handling without manual intervention.

Key integrations include Pinecone vector databases tailored per department for semantic search and retrieval-augmented generation (RAG), providing context-aware, accurate responses powered by AI. Conversation state is persisted in PostgreSQL to maintain context across interactions, while Google Drive watches for new documents to automatically update the knowledge bases, keeping information fresh without downtime.

Benefits include 24/7 scalable support, reduced response times, and minimized human involvement for routine queries, ideal for e-commerce, SaaS, or service-based businesses. Use cases span handling high-volume inquiries, onboarding new support agents with structured responses, or enhancing user satisfaction through personalized, department-focused assistance.
