Be honest. How many WhatsApp messages did you reply to late last night?
For most Indian businesses, WhatsApp isn’t just a messaging app. It’s the shop counter, the enquiry desk, the order book and the complaints department, all on one phone that is usually with the owner.
And the same questions keep coming. “Price kya hai?” “Timing?” “Location bhejo.” “Appointment milega kal?”
You don’t have to type those answers 50 times a day. Here’s how to automate WhatsApp, starting free and going all the way to a full chatbot.
Option 1: The free WhatsApp Business app
If you’re still running your business on normal WhatsApp, switch to the free WhatsApp Business app first. It has basic automation built in:
- Greeting message: auto-sent when a new customer messages you
- Away message: sent outside business hours
- Quick replies: type “/price” and your full price list appears
- Labels: tag chats as “new lead,” “paid,” “follow-up”
- Catalogue: show products or services with photos and prices
Good for: small shops and solo professionals. The limit: it runs on one phone, a few devices at most. There’s no real chatbot, and no connection to your website or CRM.
Option 2: The WhatsApp Business API (through a provider)
This is what growing businesses use. You connect through a provider like Interakt, AiSensy, WATI or Gallabox, or build directly on Meta’s Cloud API. Then you can:
- Run a chatbot with menus and buttons
- Let multiple team members reply from one number
- Send appointment reminders, order updates and payment links automatically
- Send broadcasts to customers who’ve opted in
- Connect WhatsApp to your website, CRM, Google Sheets or ads
We compare those providers side by side in best WhatsApp automation tools in India.
What it costs in India
Meta charges per message, based on message type. Current India base rates:
| Message type | Meta rate (India) |
|---|---|
| Marketing (offers, promotions) | about ₹0.86 per message |
| Utility (order updates, reminders) | about ₹0.115 per message |
| Authentication (OTP) | about ₹0.115 per message |
18% GST applies on top. Customer service replies inside the 24-hour window: the first 1,000 per number each month are free, and from 1 October 2026 replies beyond that are charged at the utility rate. Your provider’s monthly plan is separate. Meta revises these rates, so check the latest rate card before you budget.
Option 3: A custom WhatsApp bot
When your flow is specific, like qualifying a patient, checking slot availability or pulling data from your own software, a custom WhatsApp chatbot built on the API works best. No per-seat fees, and the logic fits your business exactly.
How to set up the WhatsApp API: step by step
- Verify your business in Meta Business Manager. Keep your GST certificate or business documents ready.
- Choose a phone number. It can’t stay active on the normal WhatsApp app at the same time, so many businesses use a new number.
- Get your display name approved. It has to match your business name.
- Create message templates. Any message you start (reminders, offers) needs Meta’s approval first.
- Collect opt-ins. Customers should agree to receive your messages.
- Build your flows: welcome message, menu, FAQs, handover to a human.
What to automate first
Start with messages that save time and make money:
- Instant reply to new enquiries. Speed wins customers.
- Appointment confirmations and reminders. Fewer no-shows. Salons get this built into our salon software.
- Order and delivery updates. Fewer “where is my order?” calls.
- Payment reminders. Polite, automatic, consistent.
- Review requests after service.
Here’s a real example. For a dental clinic, we built a WhatsApp flow where every enquiry, from Instagram, Meta ads or Google, gets an instant reply, a few quick questions about the problem, and then available appointment slots to pick from. The front desk only steps in when a patient actually needs a person. You can see how it works on our dental clinic software page, and the same idea runs inside our clinic management software.

Mistakes that get businesses blocked
- Spamming broadcasts to people who never opted in. Users report you, and Meta lowers your number’s quality rating.
- Bots with no way out. Always give a “Talk to a person” option.
- Ten-level menus. If a customer has to tap five times to get a price, they’ll leave.
- Robotic language. Write like your best staff member talks.
Frequently asked questions
Can I automate WhatsApp for free?
Basic auto-replies, yes, with the WhatsApp Business app. A chatbot and team inbox need the API.
Can I use my current number for the API?
Yes, but it has to be removed from the regular WhatsApp app first.
Will customers know it’s a bot?
Be upfront about it. Customers don’t mind bots that are quick and helpful. They mind bots that trap them.
