This tutorial guides the reader through building an automated SMS survey application using Laravel, PHP, and Twilio Programmable SMS. The application allows users to participate in a survey by sending messages to a designated Twilio phone number, with each message triggering a question or response to be sent back to the user via SMS. The application uses Laravel's Eloquent models and migrations to store the survey data in a database, and Twilio's Programmable SMS service to handle the communication between the user's device and the server. The application is completed by setting up routes for handling incoming requests from Twilio's webhook, generating a public URL using ngrok, updating the Twilio dashboard with the new URL, and testing the application.
