This tutorial teaches how to build a Bulk SMS application with Django and Twilio, focusing on integrating the Twilio SMS API into a Django project, sending SMS messages using the Twilio Programmable SMS API, and using Redis Queue for queuing long-running jobs. To follow along with this tutorial, one needs a Twilio account, Python 3.8 or newer, a basic understanding of Python and Django, and a text editor installed. The application is built by creating a new Django project, installing the required dependencies, defining views to send SMS messages, setting up Redis Queue for queuing jobs, and testing the application. The tutorial concludes with the entire code base available in a GitHub repository, allowing developers to continue building upon this project.
