This tutorial demonstrates the development of a WhatsApp bot that allows users to discover vegan restaurants near their location and retrieve restaurant details using Twilio's WhatsApp Business API and Node.js. The bot uses Google Maps API to obtain restaurant data and generate messages, with the goal of promoting plant-based food options and reducing greenhouse gas emissions from animal agriculture. To create the bot, developers must set up a NestJS framework, install required packages, configure environment variables, and integrate Twilio's WhatsApp Business API. The bot receives incoming messages, fetches vegan restaurants using Google Maps API, and responds with restaurant details. The tutorial provides a step-by-step guide for creating a functional WhatsApp bot that can be further enhanced and customized to suit requirements.
