This article shows you how to send a WhatsApp message from a Python script (version 3+).

Before the recipient can receive your WhatsApp message, she will need to register with the WhatsMate WA Gateway. Instructions are available on the official site. Unregistered users will never receive messages from the Gateway.

To send a WhatsApp message from a Python script, do this:

  1. Copy the following source code to your script.
  2. Customize the TODO lines:
    • Specify your gateway instance ID on line 6.
    • Specify your Client ID and Secret on lines 7 and 8.
    • Specify your target recipient on line 12. Remember to include the country code.
    • Specify your message on line 13.
  3. Make your script executable: chmod 755 send-whatsapp-text-individual.py
  4. Run the script to send your message: ./send-whatsapp-text-individual.py
