The tutorial provides instructions on how to track WhatsApp message status using the Twilio API in Node.js. To complete this task, developers need to set up a development environment with Node.js, Twilio account, MongoDB, and Ngrok. They also need to create an express app that follows the MVC pattern and add controllers as they progress through the tutorial. The code constructs a WhatsApp message body using Axios and stores the WhatsApp status, message SID, mobile number, and WhatsApp body in a database for record-keeping purposes. The developers can test their application by sending WhatsApp messages and retrieving the status of these messages using a REST client or a web browser.
