The Twilio Conversations API is a foundational component for building conversational messaging applications, and it has been used to build an engagement portal that resulted in significant improvements for businesses. This demo proof of concept shows how to configure and deploy a digital channel support and messaging application powered by the Conversations API, using the Twilio Serverless Project and Single Page Applications (SPAs) built with Vue.js. The application allows end users and agents to communicate over multiple channels, including SMS, chat, WhatsApp, and bot interactions, and it uses Twilio Sync for data persistence. The demo provides a step-by-step guide on how to set up the necessary resources, deploy the serverless project, and try out the application, and it also covers topics such as customizing and local development, webhooks, and deploying to production.
