Automate Telegram Message Processing - Separate Text and Files

Introduction

Tired of manually downloading a file through different Telegram messages? This workflow acts as a smart receptionist for your Telegram bot, automatically processing incoming messages to cleanly separate text from file attachments, getting them ready for any automation you can dream up! 📥

🎯 What This Does

This workflow solves the challenge of handling varied Telegram messages within a single automation workflow. Incoming messages can be just text, just a file, or a file with a caption. This template intelligently identifies the message type and routes it down the correct path, isolating the text content and downloading the file attachment. It's perfect for community managers, support teams, or anyone building a Telegram-powered chatbot.

🔄 How It Works

1. Listens for New Messages: The workflow starts the moment a new message is sent to your connected Telegram bot.
2. Checks Message Content: A Switch node instantly determines if the message contains:
   • Text only
   • Attachment only
   • Attachment with a message (text caption)
3. Separates Message and File: Based on the content, the workflow isolates the text (from the message or caption) and the file's metadata (file_id, file_name).
4. Downloads the Attachment: For any message containing a file, the workflow automatically downloads it, making the binary data available for the next steps in your automation.

🚀 Setup Requirements

• Credentials: You'll need a Telegram Bot API Token (Key) and Chat ID.

Set up steps

1. Create a Telegram Bot:
   • First, you need a bot. Open Telegram and send a message to the official @BotFather.
   • Send the command /newbot.
   • Follow the prompts to choose a name and username for your bot.
   • BotFather will provide you with a unique API Token. Copy this token, it's what you'll need for the next step.
2. Add Credentials to n8n:
   • In your n8n workflow, navigate to the Credentials section in the left panel.
   • Click Add credential, search for "Telegram," and select it.
   • Paste the API Token you copied from BotFather into the Access Token field.
   • Click Save to create your credential.
3. Connect Your Bot to the Workflow:
   • Back on the canvas, open the Waiting For Message (Telegram Trigger) node.
   • In the Credential for Telegram API dropdown, select the credential you just created.
   • Open the Get & Download Attachment (Telegram) node and select the same credential.
4. Activate and Test!
   • Click the Activate toggle in the top right corner of your screen.
   • Now, send a few different messages to your new bot on Telegram to test all the paths:
     • A simple text message (e.g., "Hello!").
     • A file (like a PDF or Notepad) with no text.
     • A file with a caption(message).
   • You can check the Executions tab in n8n to see each test run successfully! The NoOp nodes at the end of each path show you the final, cleanly separated data.
