Automate Telegram Group Document Sharing with PHP

Need to integrate Telegram group PDF sharing into your PHP websites, CMS platforms, or web applications? This guide shows you how to deliver PDF files to Telegram groups using PHP and the WhatsMate Telegram Gateway REST API. Perfect for PHP developers building websites, e-commerce platforms, or content management systems 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. PHP installed - Version 5.6 or later with cURL extension enabled
  4. PDF file ready - Have the document you want to send available on your server
  5. Web server access - Ability to upload and execute PHP files
  6. File permissions - PHP must have read access to the PDF file location

⚠️ 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.

📄 Server Requirements: Ensure your PHP installation has the cURL extension enabled and sufficient memory to handle PDF file reading and base64 encoding.
