Build a WhatsApp Business Chatbot with Node.js & Twilio

This beginner‑friendly course is for Indian students and career‑switchers who want a job‑ready skill in conversational APIs. You’ll build a functional WhatsApp Business chatbot that can receive messages, send automated replies, and integrate simple business logic.

By the end of the course you will have a deployed bot on Twilio’s sandbox, understand how to handle inbound/outbound messages, and be comfortable with Node.js webhooks and environment configuration.

You’ll be ready to add chatbot features to any product, showcase a live project in interviews, and start freelancing or applying for junior developer roles focused on messaging platforms.
