Build A Fax Portal with Twilio, Python and Flask

This tutorial demonstrates how to create a fax portal using Twilio's Programmable Fax service, Python 3, and Flask. The application allows users to upload a PDF file and send it to a specified Twilio phone number via fax. The tutorial covers setting up the project dependencies, configuring the Flask application with Twilio and ngrok, and creating routes for uploading files, sending faxes, and receiving status updates via SMS. The code is written in Python 3 and uses Flask as the web framework, Twilio's Python Helper Library to interact with the Programmable Fax service, and ngrok to expose the application to the internet.
