Almost every business in India already talks to customers on WhatsApp. The question is which version you should use: the free WhatsApp Business app on your phone, or the WhatsApp Business API — officially the WhatsApp Business Platform — that powers team inboxes, chatbots and bulk campaigns. Here is the practical difference, and how to decide.
The WhatsApp Business app (free)
The app is what most small businesses start with. It gives you a business profile, a catalogue, labels and a few simple automations. It is a good fit while one or two people handle chats. Its limits show up as you grow:
- Broadcast lists top out at 256 contacts, and a broadcast is only delivered to people who have saved your number.
- One phone plus up to four linked devices. There are no roles or permissions, so you can't see which team member replied.
- Automation is basic: a greeting message, an away message and quick replies. Nothing is scheduled or sent in sequence.
- No API access, so it can't connect to your website, CRM, Google Sheets or payment alerts.
The WhatsApp Business API (Business Platform)
The API is Meta's official product for businesses that message customers at scale. You reach it through a provider, and use it through a CRM or inbox instead of a single phone. It adds:
- A shared team inbox — many agents on one business number, with chats assigned and tracked.
- Chatbots and automation — instant replies, lead qualification, reminders and follow-up journeys.
- Bulk campaigns to opted-in customers using approved message templates, without the 256-contact ceiling.
- Integrations with your website, CRM, Google Sheets, webhooks and payment links.
How API pricing works
Since 1 July 2025 the platform charges per message: you pay when a template message is delivered. Templates fall into three categories — marketing, utility and authentication — and rates vary by country and category. Some messages cost nothing: ordinary replies inside the 24-hour customer service window (after a customer messages you) are free, and so are utility templates sent inside that window. Conversations that start from a click-to-WhatsApp ad open a longer free window. Meta publishes the current rates on its WhatsApp Business Platform pricing page.
What about the verified badge (the "green tick")?
A verified badge shows customers that an account really belongs to your business. Meta decides who gets it — through its assessment of notable businesses or its paid Meta Verified subscription — so no provider can promise it. It helps with trust, but you don't need it to run WhatsApp marketing or support well.
Side by side
| What you need | Business app | Business API |
|---|---|---|
| Cost to start | Free | Provider fee plus per-message charges |
| Team members | 1 phone + 4 linked devices, no roles | Many agents, shared inbox, assignments |
| Bulk messages | Broadcast lists of up to 256, saved contacts only | Template campaigns to opted-in contacts at scale |
| Automation | Greeting, away message, quick replies | Chatbots, journeys, reminders, follow-ups |
| Integrations | None | Website, CRM, Sheets, webhooks, payments |
Which one should you choose?
Stay on the app if one person answers WhatsApp, you message a few hundred customers at most, and you don't need reports or automation.
Move to the API if more than one person replies to customers, you want to send campaigns beyond 256 contacts, you run click-to-WhatsApp ads, or you want a bot to answer the questions you get twenty times a day.
One warning: avoid unofficial "bulk WhatsApp sender" tools. They work until the number is blocked — and a blocked number takes your customer conversations with it. The official API is the safe route for bulk messaging.
