How to send messages to a Telegram group from PowerShell script

Using the WhatsMate Telegram Gateway REST API



This article shows you how to send a message to a Telegram group from a PowerShell script.

You MUST obtain the secret gateway number by signing up for a Premium account before you can send a message to a Telegram group. Instructions are available on the official site.

To send a Telegram group message from your PowerShell script, do this:

  1. Create a New Group from your Telegram client.
  2. Add the secret gateway to the group. (You can add other people too!)
  3. Give your group a unique and creative name. It’s very important!
  4. Copy the following source code to your PowerShell script.
  5. Customize the TODO lines in the PowerShell script:
    • Specify your gateway instance ID on line 4.
    • Specify your Client ID and Client secret on lines 5 and 6.
    • Specify the group name on line 1.
    • Specify the content of the message on line 2.
  6. Run it.

As mentioned at the beginning of this tutorial, you will need a Premium account to call the above API. Go sign up now.

Happy coding :)
