Intelligent Telegram Customer Service Bot — Seamless Switching Workflow Between Bot and Human Agents
Key Features and Highlights
This workflow enables efficient switching between an intelligent Telegram-based customer service bot and human agents by leveraging a human-in-the-loop mechanism. The bot automatically collects user information and smoothly transfers the conversation to a human agent when necessary. After the human agent completes the service, the conversation is seamlessly handed back to the bot for continued handling. Key highlights include multi-state management (bot, human, onboarding) combined with Redis for session state storage, ensuring precise and smooth dialogue flow. The integration of OpenAI GPT models and LangChain information extraction technology facilitates natural language understanding and structured customer data collection.
Core Problems Addressed
- Automates customer information gathering to reduce the workload of initial human inquiries
- Enables dynamic switching between bot and human agents, preventing repetitive questioning and information loss
- Ensures the bot does not respond during human takeover, avoiding multi-threaded conversation conflicts
- After human service completion, feeds context back into the bot’s memory to enable subsequent automated after-sales support
- Allows users to request human assistance at any time, enhancing customer experience and service flexibility
Application Scenarios
- Customer Service Centers: Bot handles initial identity verification and requirement collection; complex issues are escalated to human agents
- Sales Consultation: Bot performs customer pre-screening and data collection; human agents focus on closing deals and in-depth communication
- After-Sales Support: Bot manages common inquiries; human agents intervene for special or complex after-sales requests
- Multi-channel customer service environments, especially businesses using Telegram as the interaction platform
Main Workflow Steps
- Message Reception and Status Check: Capture user messages via the Telegram Trigger node; query current session status (bot, human, or uninitialized) through Redis
- Bot Guides Customer Information Input: If status is initial or bot, use LangChain Agent (Onboarding Agent) to prompt the customer for name, address, reason for contact, etc.
- Information Extraction and Validation: Use the Information Extractor node to structurally extract key customer data from free text; verify completeness via decision nodes
- Trigger Human Takeover Sub-workflow: Once information is complete, invoke a sub-workflow to execute the bot-human handoff; bot sends a summary of user information to the human agent’s Telegram chat
- Status Switching and Notification: Update Redis status to human; bot pauses responses and notifies the user of the transfer to a human agent
- Human Handling and Feedback: Human agent continues communication with the user via the “Send and Wait” node; upon completion, fills in a summary and triggers status switch back to bot
- Bot Resumes Service: Bot loads the human feedback context, updates its memory store, and continues providing after-sales support
- Support for Cyclic Switching: Users can request human assistance again at any time, repeating the workflow cycle
Involved Systems and Services
- Telegram API: Messaging and user interaction platform
- Redis: Session state and chat history storage, supporting multi-state control and context management
- OpenAI GPT-4 (integrated via LangChain): Natural language understanding and generation, information extraction, dialogue management
- n8n Sub-workflow (ExecuteWorkflow): Handles bot-human handoff processes, supports asynchronous parallel execution
- Human-in-the-loop Mechanism (Send and Wait node): Enables real-time interaction switching between human agents and the bot
