This tutorial provides a step-by-step guide on how to create a WhatsApp survey application using Twilio and CakePHP. To start, you need to have PHP 8.3 or higher installed, Composer globally installed, access to a MySQL database, and a Twilio account (free or paid). You also need Ngrok installed on your computer and an Ngrok account. The tutorial then guides you through creating a new CakePHP project, connecting to the database, creating tables for questions and answers, setting up environment variables, retrieving Twilio API credentials, setting up the Twilio WhatsApp sandbox, installing Twilio's PHP Helper Library, creating a survey controller, configuring the router, and testing the application. Once set up, you can invite users to participate in the survey, receive their responses, and view collected statistics. The tutorial concludes by emphasizing the effectiveness of using WhatsApp surveys for gathering valuable feedback from your audience.
