This tutorial teaches users how to automate shift scheduling using Twilio SMS and Google Sheets. The system allows employees to request shift swaps via SMS, which are then confirmed by the second employee through an SMS reply. Once confirmed, the shift is updated on Google Sheets. To set up this automation, users need a Twilio account, a Google Cloud account with Google Sheets enabled, an ngrok account, and Node.js installed on their system. The tutorial guides users through setting up their project, creating environment variables, integrating Google Sheets, setting up the SMS endpoint, and testing the application. The system is ideal for small businesses looking for a low-maintenance way to manage schedules without steep learning curves.
