Send PDF Files to Telegram Groups in Python - Complete Guide

Automate Telegram Group Document Sharing with Python

Need to integrate Telegram group PDF sharing into your Python applications for data science, automation, or machine learning workflows? This guide shows you how to deliver PDF files to Telegram groups using Python and the WhatsMate Telegram Gateway REST API. Perfect for Python developers building data pipelines, automation scripts, or AI applications that need document delivery to group chats.

📋 Prerequisites

Before you begin, ensure you have:

1. A WhatsMate Telegram Gateway account - Required for API access
2. Group membership - The gateway must be a member of the target Telegram group
3. Python 3 installed - Version 3.6 or later recommended
4. PDF file ready - Have the document you want to send available locally
5. Requests library - Install via pip install requests

⚠️ Important: The gateway must be a member of the Telegram group you want to send messages to. The group admin phone number is used to uniquely identify the group.

📄 Python File Handling: The script uses Python’s built-in file operations and base64 encoding, ensuring compatibility across different platforms and Python versions.

📝 Step-by-Step Implementation

Follow these steps to send your first PDF document to a Telegram group from a Python script:

1. Copy the Python Source Code

Start by copying the following source code into your Python file:

2. Configure a few Parameters

Customize these key parameters in the Python code:

• Line 8: Replace "YOUR_GATEWAY_INSTANCE_ID_HERE" with your Telegram gateway instance ID
• Line 9: Replace "YOUR_OWN_ID_HERE" with your Client ID
• Line 10: Replace "YOUR_OWN_SECRET_HERE" with your Client Secret
• Line 14: Replace 'Muscle Men Club' with the name of your target Telegram group
• Line 15: Replace '19159876123' with the phone number of the group admin (including country code)
• Line 16: Replace "../assets/subwaymap.pdf" with the path to your PDF file
• Line 17: Replace "anyname.pdf" with the desired filename for the document
• Line 18: Replace "Check this out" with an optional caption for your PDF

3. Install Required Dependencies

Ensure you have the requests library installed:

pip install requests

Note: The base64 module is included in Python’s standard library, so no additional installation is needed.

4. Make the Script Executable

Set execute permissions on your script:

chmod 755 send-telegram-pdf-group.py

5. Run Your Python Script

Execute the script to deliver your PDF to the Telegram group:

./send-telegram-pdf-group.py

Alternative: If the script isn’t executable, run it with Python directly:

python3 send-telegram-pdf-group.py

🔧 Common Use Cases

This Python integration is ideal for:

• Data science workflows - Send analysis reports, visualization PDFs, or research papers to Telegram groups
• Machine learning pipelines - Deliver model documentation, performance reports, or research findings to teams
• Automation scripts - Integrate with Python automation tools for scheduled PDF delivery
• Document processing applications - Combine with PDF generation or processing libraries for automated delivery
• IoT and monitoring systems - Send system documentation or log reports as PDFs to admin groups
