More than 500 million Indians use WhatsApp, and most of them would rather message a business than call it. The free WhatsApp Business app works for a small shop, but once several staff need the same number, or you want chatbots, campaigns and CRM integration, you need the WhatsApp Business API. This guide explains what it is, how pricing works, and how to get started in India.
What is the WhatsApp Business API?
The WhatsApp Business API, officially the WhatsApp Business Platform from Meta, lets a business connect its WhatsApp number to software instead of a single phone. That software can be a shared team inbox, a chatbot, your CRM or your order system. Most businesses use it through the official Meta Cloud API and a platform such as the BitVoice Social Media Platform.
WhatsApp Business app vs WhatsApp Business API
| WhatsApp Business app | WhatsApp Business API | |
|---|---|---|
| Users | One phone, a few linked devices | Unlimited agents on one number |
| Chatbots | Quick replies and greeting only | Full chatbot flows and AI |
| Bulk messages | Broadcast lists to saved contacts | Campaigns with approved templates to opted-in customers |
| Integrations | None | CRM, ERP, online shop, helpdesk via API |
| Reports | Basic | Conversation and agent reports |
| Verified business | Possible | Possible, with official business profile |
| Best for | Very small businesses | Growing teams and enterprises |
What can you do with the WhatsApp Business API?
- Customer support: a shared inbox where every agent answers from the same number, with chats routed to the right department.
- Chatbots: answer common questions, take orders or book appointments automatically, and hand over to a person when needed.
- Notifications: order confirmations, delivery updates, appointment reminders and payment receipts.
- Campaigns: offers and announcements to customers who have opted in, personalised with their name and details.
- WhatsApp calls: customers can call your business on WhatsApp, and your team answers in the same system.
- CRM integration: see customer history next to the chat, and let your CRM or ERP send WhatsApp messages automatically.
How WhatsApp Business API pricing works in India
Meta charges for business-initiated template messages, and the rate depends on the template category:
- Marketing: offers, product launches, re-engagement.
- Utility: order updates, appointment reminders, account alerts.
- Authentication: one-time passwords.
When a customer messages you, a 24-hour customer service window opens. Replies within that window are free-form and do not need a template. Meta publishes its current rates for India on its developer site, and they change from time to time, so check them before planning a large campaign. On top of Meta’s charges, your platform provider charges for the software: the inbox, chatbot, campaigns and integrations.
Rules you must follow
- Opt-in: message only customers who have agreed to hear from you on WhatsApp.
- Approved templates: every business-initiated message uses a template approved by Meta.
- Quality rating: if many customers block or report your messages, Meta lowers your quality rating and messaging limits. Send useful messages, not spam.
- 24-hour window: outside it, you can only send templates.
How to get started
- Choose a number that is not already active on the WhatsApp app, or migrate it.
- Verify your business in Meta Business Manager.
- Connect the number to your platform through the official Cloud API.
- Create templates for your notifications and get them approved.
- Set up your inbox and chatbot, add your team, and go live.

FAQs
Is the WhatsApp Business API free?
No. Meta charges per template message by category (marketing, utility and authentication), while replies to customers within the 24-hour customer service window are free. Your platform provider also charges for the software.
Can I use my existing WhatsApp number for the API?
Yes, but a number can be active on either the WhatsApp app or the API, not both at once. It can be migrated from the app to the API.
Can multiple agents use one WhatsApp number?
Yes. With the API and a shared inbox, any number of agents answer from the same WhatsApp number, with chats assigned by department.
Can I send bulk WhatsApp messages with the API?
Yes, to customers who have opted in, using Meta-approved templates. The BitVoice platform sends personalised campaigns from CSV or Excel lists with delivery reports.
What is the difference between WhatsApp Business app and API?
The app runs on one phone for a small business. The API connects WhatsApp to software, so teams, chatbots, campaigns and CRM integrations work on one number.
