How much does WhatsApp automation cost in India?
Cost has three parts: Meta's message fees, platform fees and AI cost. Meta charges per delivered message, and marketing costs far more than utility. Add 18% GST. Check the current rate card, because Meta changes rates.
Worked example (Meta fees only): 2,000 marketing messages × ₹0.86 = ₹1,720. 5,000 utility messages × ₹0.115 = ₹575. Total about ₹2,295, plus GST.
What are the rules for WhatsApp AI agents in India?
You need opt-in, approved templates outside the 24-hour window, and safe data handling under the DPDP Act.

Per Meta's opt-in policy, with your name clear.

Marketing, utility or authentication.

Meta does not allow general-purpose AI chat assistants on the Business API. India's DPDP Rules were notified in November 2025, and most duties apply from May 2027.
What can a WhatsApp AI agent not do?
It cannot fix a weak offer or message people who did not opt in. Keep a person for big prices, complaints and refunds, and review chats weekly.
