Quick Answer
A WhatsApp chatbot is an automated assistant that replies to customers on your WhatsApp business number. It answers common questions, collects details, shows options as buttons and lists, and passes the chat to a human agent when needed. In India, businesses run chatbots on the official WhatsApp Business Platform; replies sent after a customer messages you fall inside Meta's 24-hour customer service window, while messages you start need an approved template.
What can a WhatsApp chatbot do for your business?
Most WhatsApp conversations repeat the same few questions. A chatbot handles those instantly and leaves your team free for the chats that need a person.
Answer FAQs instantly
Timings, prices, locations, policies and documents, answered in seconds at any hour with text, images or PDFs.
Capture and qualify leads
Ask a few questions, tag the lead by interest and budget, and route hot leads to sales so they follow up first.
Order and delivery status
Let customers check orders, returns and refunds themselves by connecting the bot to your store or CRM through the API.
Bookings and appointments
Offer slots as buttons, confirm the booking and send utility reminders before the appointment.
Hand over to a human
When a customer asks for an agent, or the bot cannot help, the chat moves to the shared team inbox with full history.
Re-engage opted-in users
Follow up with approved marketing or utility templates to customers who opted in, then let the bot handle their replies.
How a WhatsApp chatbot works
Every chatbot conversation follows Meta's rules on who starts the chat and how it is billed.
| Stage | What happens | Meta rule |
|---|
| Customer messages you | From your website button, a QR code, a Click-to-WhatsApp ad or a missed call flow | Opens a 24-hour customer service window |
| Bot replies | Menus, buttons, lists, media and questions guide the customer | Free-form service replies are allowed inside the window |
| Agent takes over | The chat appears in the team inbox with the full conversation | Same window; agents reply as service messages |
| You follow up later | Reminder, order update or offer after the window has closed | Must use an approved marketing, utility or authentication template |
Meta bills per message by category, including service replies from 1 October 2026. Inbound messages stay free. Check current rates on WhatsApp pricing and what changed on the WhatsApp API pricing change 2026 page.

If a WhatsApp message cannot be delivered, fall back to DLT-compliant SMS or RCS from the same wallet.
Official platform
SMSGatewayHub is a Meta Tech Provider on the official WhatsApp Business Platform, so your number is not at risk from unofficial tools.
Rule-based chatbot or AI chatbot?
A rule-based WhatsApp chatbot follows the menus and buttons you design. It is predictable, easy to approve internally and ideal for order status, bookings, lead forms and FAQs with clear answers. An AI chatbot understands free-text questions and can answer from your knowledge base, which helps when customers ask the same thing in many different ways or in mixed languages.
Many Indian businesses start with a rule-based flow for the top five questions and add AI later. If you want natural-language answers across WhatsApp, RCS and SMS, see our AI automated chatbot.

Meta policy checklist for WhatsApp chatbots
Following WhatsApp Business policies keeps your quality rating high and your number safe.
- Message customers first only if they have opted in to hear from you on WhatsApp.
- Use approved templates for any message you start outside the 24-hour window.
- Always offer a clear way to reach a human, and honour opt-out requests promptly.
- Keep utility templates free of offers so Meta does not recategorise them as marketing.
- Do not ask for full card numbers, passwords or OTPs inside the chat.
- Collect opt-ins from your website, checkout, forms or a missed call to WhatsApp auto reply flow.
Frequently Asked Questions
What is a WhatsApp chatbot?
A WhatsApp chatbot is automated software that replies to customers on your WhatsApp business number. It answers common questions, collects details through buttons and lists, and hands the chat to a human agent when needed.
Do I need the WhatsApp Business API for a chatbot?
Yes. Chatbots, multi-agent inboxes and integrations run on the WhatsApp Business Platform (API), not on the free WhatsApp Business app. SMSGatewayHub provides access to the platform and helps with Meta business verification.
Can I build a WhatsApp chatbot without coding?
Yes. The SMSGatewayHub chatbot builder lets you design flows with buttons, quick replies and media without code. Developers can still connect the bot to a CRM or store through the API and webhooks.
Can customers talk to a human instead of the bot?
Yes. You decide when the bot hands over, for example when a customer types agent or the bot cannot answer. The conversation then moves to the shared team inbox with its full history.
How is a WhatsApp chatbot charged?
Meta charges per message by category. Replies inside the 24-hour customer service window are service messages, which Meta bills per message from 1 October 2026, while template messages you start are billed as marketing, utility or authentication. Inbound messages are free.
What is the difference between a chatbot and an AI chatbot?
A rule-based chatbot follows the menus and buttons you design, which suits clear tasks like order status or bookings. An AI chatbot understands free-text questions and answers from your content, which helps when customers phrase questions in many ways.
