Build a Simple Customer Support Channel with WhatsApp

This article demonstrates how to build a WhatsApp call center using the Vonage API, with the goal of providing better customer service by making interactions more familiar and engaging for customers. The tutorial shows how to set up a demo app that uses emojis to identify threads between multiple chats, allowing agents to easily distinguish between different customers. To complete the tutorial, users need to have a Vonage API account, a WhatsApp Business Account or a Messages API Sandbox, as well as a public URL for their application. The tutorial guides users through setting up the application, configuring webhooks and credentials, and starting the application locally. Once set up, users can start sending messages to customers and receive responses with emojis that indicate which customer they are responding to.
