    How to Make a Kid Feel Like a Hacker With the Twilio CLI header - How to Make a Kid Feel Like a Hacker With the Twilio CLI

    Summer school just ended which means - school's out, scream and shout! Kids are enjoying their remaining weeks of summer before starting back again.

    Oh how I miss being a kid with forced breaks and recess time. Recently I visited an elementary school during their summer session and felt the nostalgia of being an innocent kid. Life was so simple when the main concern was having enough time to be cool and not get caught passing notes across the classroom! Since I grew up in a low-income community, I decided to give back and show the classrooms a fun presentation on what it's like to work in the tech industry and write code!

    With the help of Twilio and the command line, I was able to show the elementary school students how to feel like a hacker by typing some lyrics on the computer, pressing a few buttons, and …

    Automate and Optimize Healthcare Appointment Outreach Using Twilio Appointment Management with EHR Integration Quick Deploy App.png

    A new Quick Deploy app is now available for healthcare provider organizations! The app packs together the core components of a deployable prototype for automated, two-way appointment management with EHR integration.

    Deploy the app here.

    This app is intended for prototyping and testing purposes only. Not for use in production environments!

    One of the most critical elements of delivering high-quality healthcare is an efficient scheduling and appointment management process. In the US alone, missed appointments cost the healthcare system $150B each year. Appointment outreach is an easy and cost-effective way to reduce no-shows, yet many available solutions for sending out these reminders are batched, delayed, and lack flexibility.

    Twilio is focused on helping you find a solution that overcomes these challenges and best fits your needs! If your organization is exploring building an in-house solution, Twilio’s real-time Messaging API can be integrated with your Electronic Health Record (EHR) …

    Proxy your phone number with Twilio Programmable Voice and Twilio Functions Header

    Using Twilio's Super Network, you can quickly buy phone numbers from around the world. You can even specify a specific area code to buy a phone number that is local to a certain state, territory, or region.

    With Twilio Voice, you can quickly integrate voice communication into your applications. For the application in this tutorial, you'll use Twilio phone numbers, Twilio Voice, and Twilio Functions to create a proxy phone number!

    What do I mean by a proxy phone number? Before explaining that, I will discuss a similar concept. In web development, there's a concept of "reverse proxies". When you send HTTP requests to a reverse proxy, the reverse proxy forwards the traffic to a web server on a private network. This way the web server still serves a website but isn't exposed directly to the internet adding benefits like security, performance enhancements, and much more.

    Expose a local Django server to the Internet using ngrok django_and_ngrok.jpg

    Django comes with a lightweight server that allows you to serve your project on your local machine at http://localhost:8000. This is a great way to test and troubleshoot your application code.

    Your local server isn't exposed to the real Internet, though, so your Django project can't receive requests from an external source, such as a Twilio webhook.

    For development purposes, you may need to test that your app code properly handles requests from external sources. To do that, you must expose your app to the Internet.

    What is ngrok?

    The ngrok utility generates public URLs that map to your local server, enabling you to test how your development code handles requests from external sources. Read more about ngrok and how it works in the official documentation.

    Prerequisites

    All you need for this tutorial is an existing Django project running on Python 3.

    Install the pyngrok package
