Automated Telegram Support Bot for Departments

This n8n workflow creates an intelligent support bot on Telegram to assist users with different departmental queries such as Return Policy, Tech Support, and Billing. It starts with a Telegram trigger listening for user messages, then guides the conversation based on specific commands. The workflow manages user sessions with PostgreSQL, storing user choices and activity states. Depending on user input, it responds with relevant information, updates the user’s department status in the database, and retrieves or stores data in Pinecone vector stores tailored for each department. It also integrates document processing from Google Drive to enhance responses by extracting and embedding document content for subsequent AI-based assistance. This setup is ideal for organizations seeking automated, department-specific customer support and information retrieval via Telegram, combined with data and document management through Google Drive and Pinecone. The workflow exemplifies seamless multi-service automation, combining real-time messaging, database management, document processing, and vector similarity search, providing a scalable and intelligent support system.
