Motivation 💡

There is an ocean of information about COVID-19 on the Internet, but WhatsApp still remains the primary medium for clutter-free information and communication for a vast majority of people.

What I built 🚀

A location based WhatsApp bot powered by Twilio that helps users track COVID-19 cases from all over India, as well as get information about essential services to help them be better prepared to deal with the pandemic.

How I built it

Tech Stack

The project is developed using Python3.8 with the Flask web microframework, and uses Twilio's Programmable SMS API for WhatsApp.
To offer the location based features of our bot we used the geopy OpenStreetMap library.
We used Heroku as our platform to build and deploy our code to Production where we used Gunicorn as our web server.
To send and receive messages with users, we Twilio's Sandbox for WhatsApp configured with our Heroku app's URL endpoint as a webhook.

To get more detailed instructions on how to set up and run the project locally, and deploy it on Production, checkout the README.md file from the project repository link above.
