For most Indian customers, WhatsApp is the first place they go to ask a question. The free WhatsApp Business app works well for a single shop owner, but it breaks down once several staff need to reply, leads need to reach a CRM or you want to send automatic order updates. That is where the WhatsApp Business API (officially the WhatsApp Business Platform) comes in.
App versus API: the real difference
The app runs on one phone (with a few linked devices). The API has no screen of its own — it connects WhatsApp to software. That software might be a shared team inbox, a chatbot, your Shopify store or your ERP. With the API you can:
- Let many agents answer from one number
- Send automatic notifications such as payment receipts, delivery updates and appointment reminders
- Run an AI chatbot that answers common questions and captures leads
- Keep every conversation linked to the right customer record
How pricing works
Meta charges per message for certain categories, such as marketing and utility templates, while customer-initiated service conversations are treated differently. Rates differ by category and change from time to time, so always check Meta's current pricing page. On top of that, most businesses pay a monthly fee to a solution provider (a Business Solution Provider or BSP) for the inbox and automation tools.
Templates and opt-in
Any message you start must use a pre-approved template. Promotional templates should only go to people who have opted in to hear from you. Sending unsolicited bulk messages is the fastest way to get your number restricted. Collect opt-in on your website forms, checkout page or in the first chat.
A sensible rollout plan
- Pick one high-volume use case — order updates or lead replies are good starters.
- Verify your Meta Business Manager and display name.
- Write three to five templates and get them approved.
- Connect the API to the system that holds the data (store, CRM or ERP).
- Add a chatbot only after the basics work, and always offer a "talk to a person" option.
FAQs
Can I keep my existing WhatsApp number?
Yes, but the number must be removed from the WhatsApp app before it can be registered on the API. Back up important chats first.
Is the green tick necessary?
No. Verified badges are optional and are granted at Meta's discretion. A clear display name and profile matter more for trust.
Can the API send messages to anyone?
Only to people who have opted in, and only with approved templates when you start the conversation.
