This tutorial provides a comprehensive guide on building a real-time SMS status tracking and logging system using Go and Twilio. The application allows users to track the lifecycle of an SMS message in real-time, including queued, sent, delivered, or undelivered status updates. The system uses Twilio's Programmable Messaging API to send and receive SMS messages, with the ability to log each event in a CSV file for further processing. The Go application is built using the go mod init command, installing dependencies such as Twilio's official Go Helper Library, GoDotEnv, and GoCSV. The application exposes its local server to the public internet using ngrok, allowing users to configure the webhook in their Twilio dashboard. The system also includes features for sending SMS messages, viewing logged status updates, and logging each event in a CSV file. With this tutorial, developers can build a robust and efficient SMS tracking system that captures incoming messages and status updates, logs them cleanly, and displays them in real-time through a web interface.
