TG Bot Customer Service System Architecture Analysis: How WebSocket, Routing, and Translation Work Together

When a team relies on Telegram Bot for customer service and operations, the technical architecture is often overlooked—until issues like message delays, agent conflicts, or translation failures arise. Understanding the TG Bot customer service system architecture not only helps you quickly troubleshoot problems but also guides you in choosing the right tool for your team size. Using TG-Staff as an example, this article breaks down the complete chain from Bot integration, WebSocket real-time communication to session routing and automatic translation, and explains the design logic behind it.

Why Understanding the Technical Architecture of TG Bot Customer Service System Matters

Operators don’t need to be backend engineers, but understanding the four key layers of the architecture brings practical benefits:

  • More accurate selection: Knowing the difference between Webhook and Polling helps you judge why certain platforms have better real-time performance.
  • More efficient troubleshooting: When a message doesn’t arrive, you can distinguish whether it’s a Bot Token configuration issue, WebSocket disconnection, or translation API quota exhaustion.
  • More proactive optimization: Understanding how routing rules distribute traffic allows you to adjust “round-robin” or “online-first” modes based on team scheduling.
  • Smoother communication: When discussing requirements with the development team, you can accurately describe modules like “connection, routing, translation, risk control,” reducing information loss.

Below, we start from the outermost Bot integration layer and dive deeper step by step.

Bot Integration Layer: Telegram Bot API and Webhook Mechanism

All customer service sessions start when the Telegram Bot receives a user message. TG-Staff uses the Webhook mode to integrate with the Telegram Bot API for real-time message forwarding.

Webhook vs. Polling: Why TG-Staff Chooses Webhook Mode

ModeWorking PrincipleReal-time PerformanceResource Consumption
PollingServer requests new messages from Telegram API every few secondsLatency depends on polling interval (usually 1-5 seconds)Continuous connection and bandwidth usage
WebhookTelegram server actively pushes to a specified URL when a new message arrivesMillisecond-level pushResources consumed only when messages arrive

TG-Staff uses Webhook mode for two reasons:

  1. Real-time performance: After a user sends a message, the Telegram server almost immediately pushes it to TG-Staff’s Webhook endpoint, so agents see new sessions in the web portal with almost no delay.
  2. Resource efficiency: No need to build long connections or scheduled tasks; the platform automatically handles Webhook signature verification and message queuing, reducing server overhead.

Architecture Tip

In Webhook mode, the Bot must have its Webhook URL correctly set in BotFather. TG-Staff Console automatically completes the configuration; users only need to add the Bot Token in “Project Management” without manually handling the Webhook URL or SSL certificate.

Decoupled Design of Bot and Agent Portal

In the TG-Staff architecture, the Bot is only responsible for sending and receiving messages, and does not participate in agent logic, session assignment, or translation processing. This decoupled design brings two benefits:

  • Multiple agents can log in simultaneously: Even if 20 agents are online at the same time, the Bot only needs to maintain one Webhook connection, and message reception stability is not affected by an increase in the number of agents.
  • Flexible Bot configuration: Changing the Bot Token, modifying the Bot avatar or description (directly edited in the TG-Staff console) does not affect the operational status of the agent portal.

Real-time Two-way Chat: How WebSocket Drives Conversations Between Agents and Users

When a user message reaches the TG-Staff backend through the Bot access layer, the next step is to push it to the agent portal. The key technology here is WebSocket—a full-duplex communication protocol that allows the server to actively push data to the client.

The message flow path is as follows:

  1. User → Bot → Webhook → TG-Staff Backend → WebSocket → Agent Portal
  2. Agent → WebSocket → TG-Staff Backend → Telegram Bot API → User

WebSocket maintains a persistent connection between the agent portal and the backend. When an agent replies to a message, the message is sent to the backend via WebSocket, which then sends it to the user through the Telegram Bot API. The entire process completes within 1-2 seconds.

Important Notes

WebSocket connection stability is affected by network conditions. It is recommended that agents use wired networks or stable Wi-Fi to avoid frequent disconnections causing message delays. If the agent’s network is poor, try turning off VPN or switching to a 4G/5G network.

Message Status Synchronization Mechanism: TG-Staff’s backend tracks the status of each message (sent, delivered, read). When the WebSocket disconnects, messages are temporarily stored in the server queue. When an agent comes back online, unread messages are automatically pulled to ensure no customer inquiries are missed.

For teams handling multiple user sessions simultaneously, the routing module is responsible for deciding “which agent should handle a new user.” TG-Staff offers two routing rules and a unique traffic attribution tool—Diversion Links.

Two Modes of Routing Rules and Their Use Cases

ModeImplementation PrincipleUse Case
Round Robin (Default)Polls agents in order; each new session is assigned to the next agent in lineScenarios with a fixed number of agents where workload needs to be evenly distributed (e.g., shift-based customer service teams)
Online FirstPrioritizes assigning to currently online agents; falls back to round robin if all agents are offlineScenarios with non-fixed agents requiring quick response (e.g., startup teams, part-time customer service)

Configuration Recommendations:

  • If your team has a clear shift schedule (e.g., 3 agents on morning shift, 2 on evening shift), using Round Robin can prevent overload on some agents that may occur with Online First mode.
  • If agents are part-time with irregular online hours, using Online First ensures that user messages are handled by the fastest available agent.

Diversion Links are a unique feature of TG-Staff: they generate a https://app.tg-staff.com/{code} short link. When a visitor clicks it, they are redirected to the Telegram Bot, and the following information is captured:

  • IP Address: Infers the visitor’s geographic location
  • Browser User-Agent: Identifies device type and operating system
  • Source URL: Records which page the visitor clicked the link from (e.g., ad landing page, social media post)
  • Custom Parameters: Supports utm_source, campaign_id, etc., for ad attribution

This information is displayed alongside the session in the agent portal’s user profile. For example, an agent can see “User from Google Ads → keyword ‘crypto wallet’ → mobile device → US IP” and adjust their response strategy accordingly.

Full Chain: Ad campaign → User clicks diversion link → Redirected to Telegram Bot → Bot auto-replies → Assigned to an agent based on routing rules → Agent sees attribution data in user profile.

Automatic Translation Service: Technical Implementation of Multilingual Customer Service

For cross-border teams, multilingual customer service is a must. TG-Staff’s automatic translation module embeds a translation engine in the message flow, allowing agents to handle multilingual conversations without switching tools.

Translation Trigger Timing and Message Flow

Translation can be configured independently in two directions:

  • Translate on Receive: When a user sends a message in Russian, TG-Staff’s backend calls the translation API, and the agent sees a Chinese translation in the portal. The original message and translation are displayed side by side, and the agent can click to view the original.
  • Translate on Send: When an agent types a reply in Chinese, the backend automatically translates it into English (or the user’s language) before sending it via the Telegram Bot API.

The two directions do not interfere with each other. For example, an agent can enable only “Translate on Receive” to understand the user and reply in English directly, or enable bidirectional translation for a seamless experience where the agent uses Chinese and the user uses their native language.

Switching Mechanism for Professional Translation Engines

PlanAvailable Translation EnginesDaily Quota
StandardAI Translation (Default)Quota applies (see official plan page for details)
ProfessionalAI Translation / DeepL Professional Translation / Google Professional TranslationUnlimited translation (subject to official site)

Professional plan users can select the translation engine in the project settings. The system automatically calls the corresponding API based on the configuration: when DeepL is selected, messages are sent to the DeepL API for translation and returned; when Google is selected, the Google Cloud Translation API is used. Switching engines takes effect immediately without restarting the Bot or reconfiguring.

Content Moderation and Wallet Address Monitoring: Architecture Design of the Internal Control Module

The content moderation module applies interception logic before an agent sends a message, suitable for teams requiring compliance and internal control (e.g., Web3, exchanges, NFT projects).

Workflow:

  1. The agent edits a message in the portal and clicks “Send”
  2. The frontend sends the message content to the backend moderation engine
  3. The moderation engine matches against risk phrases associated with the current project (e.g., “payment address,” “TRC20 address,” or specific wallet address fragments)
  4. If a risk phrase is matched → a pop-up prompts the agent for double confirmation or blocks sending
  5. All trigger records are written to the audit log: including agent name, session ID, trigger time, and matched risk phrase

Special Implementation for Wallet Address Monitoring: Administrators can configure regular expressions (e.g., `^T[A-Za-z1-9]33Message Status Synchronization Mechanism: TG-Staff’s backend tracks the status of each message (sent, delivered, read). When the WebSocket disconnects, messages are temporarily stored in the server queue.

  2. The frontend sends the message content to the backend moderation engine

  4. If a risk phrase is matched → a pop-up prompts the agent for double confirmation or blocks sending
  5. All trigger records are written to the audit log: including agent name, session ID, trigger time, and matched risk phrase

Special Implementation for Wallet Address Monitoring: Administrators can configure regular expressions (e.g., to match TRC20 addresses) or address fragments (e.g., T9eDm...) in the risk phrase settings. When an agent’s message contains a matching pattern, the system automatically intercepts it. This prevents leakage or incorrect sending of payment addresses due to agent error or malicious intent.

Audit logs can be viewed under “Content Moderation → Trigger Records” and filtered by agent, time range, and risk phrase, making it easy for compliance teams to trace.
