Automate Telegram Group Image Sharing with Google Apps Script

Need to integrate Telegram group image sharing into your Google Workspace automation, Sheets workflows, or Drive-based processes? This guide shows you how to deliver images to Telegram groups using Google Apps Script and the WhatsMate Telegram Gateway REST API. Perfect for Google Workspace users automating business processes, data workflows, or team collaboration that needs visual content 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. Google account with Drive access - To store and access image files
4. Image file in Google Drive - Have the image you want to send uploaded to your Drive
5. Basic Google Apps Script knowledge - Familiarity with script editor and functions

⚠️ 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.
