Workflow Name

🤖 Telegram Messaging Agent for Text/Audio/Images

Key Features and Highlights

This workflow implements a multimodal intelligent Telegram message processing agent capable of receiving and automatically handling text, voice (audio), and image messages from Telegram. By integrating OpenAI’s language models (such as GPT-4o-mini), it achieves intelligent message classification, transcription (speech-to-text), image analysis, and content understanding, ultimately generating context-aware automated replies based on the message content.

Core Problems Addressed

  • Automates processing of various message types received by a Telegram Bot, enhancing interaction efficiency
  • Utilizes Webhook for real-time message push and processing, avoiding resource waste caused by polling
  • Leverages AI models for intelligent message content classification and comprehension, supporting differentiation between task-related and general conversations
  • Automatically transcribes voice messages and analyzes image content, enriching the bot’s interaction experience and functional depth
  • Implements user authentication to ensure secure and targeted message processing

Application Scenarios

  • Enterprise customer service automation: Automatically identifies user needs and quickly responds to text, voice, or image inputs
  • Intelligent assistant bots: Supports multimodal inputs to improve the naturalness and convenience of user interactions
  • Task management tools: Automatically recognizes and categorizes task-related messages to assist task creation and management
  • Content review and analysis: Automatically analyzes image and audio content to support content monitoring and management
  • Reference template for developers building Telegram Bots, simplifying Webhook configuration and message handling workflows

Main Workflow Steps

  1. Webhook Message Reception: Listens to Telegram events via Webhook for real-time message intake.
  2. User Authentication: Verifies sender information to ensure message legitimacy.
  3. Message Type Routing: Routes messages based on type (text, voice, image) for specialized processing.
  4. Voice Processing: Downloads voice files and calls OpenAI’s transcription API to convert speech to text.
  5. Text Processing: Extracts text content and invokes the language model for classification to determine if the message is task-related.
  6. Image Processing: Retrieves image files, converts them to Base64 format, and calls OpenAI for image content analysis.
  7. Intelligent Classification and Reply: Sends task-related or general message replies based on AI classification results.
  8. Error Handling: Sends error notifications for unrecognized or unprocessable messages.
  9. Webhook Configuration Management: Supports setup and status queries for Webhooks in both testing and production environments.
