How does WhatsApp automation work for a small business in India?
The short answer
WhatsApp automation sends replies and updates for you. Start with the free WhatsApp Business app for simple automatic messages. Move to the paid WhatsApp Business Platform when an AI agent must reach your orders or calendar. Customers must agree to hear from you, and automated chats must offer a way to reach a person.
- Up to 24 hoursWindow open. Your AI agent can reply freely.
- After 24 hoursWindow closed. Approved templates only, until the customer writes again.
The WhatsApp Business app or the Platform?
Two official routes. The WhatsApp Business app is free to use, with greeting messages, away messages and quick replies. The WhatsApp Business Platform, often called the API, connects WhatsApp to your own systems.
| Question | WhatsApp Business app | WhatsApp Business Platform |
|---|---|---|
| Cost | Free to use | Meta charges per delivered message, and a partner may add fees |
| AI | Meta's Business AI, for eligible businesses | Your own AI agent, or Meta Business Agent |
| Best for | Replying by hand, with a little help | Many chats, or work that needs an AI agent |
Three WhatsApp rules to follow
WhatsApp sets these rules in its Business Messaging Policy, updated 23 September 2026.
- Customer permission. Message only people who gave you their number and agreed to hear from you, and stop when they ask.
- The 24-hour window. You can reply freely, with automation, for 24 hours after a customer's last message. After that, send only approved templates.
- A way to reach a person. Automated replies need a clear route to help, such as a transfer to a person, a phone number or email.
What WhatsApp charges since 1 October 2026
Per-message pricing. Meta charges only for delivered messages, and messages customers send you are free. Each business number gets 1,000 free service messages a month, which are your replies inside the 24-hour window. Charges start at the 1,001st.
Templates, such as offers, are charged by type, and rates can change each quarter.

Is an AI agent allowed on WhatsApp?
Yes, for your own customers. Meta's Platform terms bar AI providers when AI is the main offering, such as a general-purpose assistant. Meta's pricing page says third-party AI can power service messages.
Can I send bulk WhatsApp messages to customers?
Only to people who agreed to hear from you. On the Platform, offers go out as approved marketing templates, Meta charges for each delivered message, and you must stop when someone asks.
Does WhatsApp have its own AI agent?
Yes. Meta offers Business AI in the WhatsApp Business app to eligible Indian businesses. In June 2026, Meta said its agent is free to start, with paid subscriptions to follow.
Can NeuraFlow set up WhatsApp automation?
Yes. NeuraFlow builds AI agents that talk to your customers on WhatsApp and your website. NeuraFlow Zap is our own product for WhatsApp workflows.
