How to Receive Images on WhatsApp Using Flask and Twilio

The tutorial explains how to create a Python application using the Flask web framework that receives and handles images sent by users on WhatsApp, using the Twilio WhatsApp Business API. The application is developed in a virtual environment and uses the ngrok utility to make it temporarily accessible over the Internet for testing purposes. The webhook endpoint extracts information from incoming messages, saves images locally if they are included, and sends responses back to the user through WhatsApp. The tutorial also covers setting up a development server, configuring the WhatsApp webhook, and testing the application.
