What is an AI chatbot for WhatsApp?
An AI chatbot for WhatsApp is an automated conversational agent that runs on WhatsApp Business API, enabling businesses to send and receive messages at scale with AI-powered responses. Unlike personal WhatsApp, the Business API supports automation, integrations, and multi-agent access. WhatsApp messages have a 98% open rate compared to roughly 20% for email, making it one of the most effective communication channels. AI chatbots on WhatsApp handle everything from customer support and order updates to lead qualification and marketing campaigns. Setting up requires a WhatsApp Business API provider like ManyChat or WATI.

How to get started with a WhatsApp chatbot
First, you need a WhatsApp Business API account -- this is different from the regular WhatsApp Business app. Sign up through an official API provider like ManyChat, WATI, or AiSensy, who handle the Meta verification process. You will need a dedicated phone number and a verified Facebook Business account. Once approved, configure your AI chatbot with welcome messages, FAQ responses, and conversation flows. Be aware of WhatsApp's conversation-based pricing: Meta charges per 24-hour conversation window, with rates varying by country and message category (utility, marketing, authentication). Provider markup typically adds 15-20% above Meta's rates.
