WhatsApp Business app vs API: which does your small business need?
The free app is enough for a lot of small businesses, until messages pile up, a second person needs to reply, or you want to reach every customer at once. Here is where the line falls, and how to cross it without losing your number.
The short answer
Stay on the WhatsApp Business app if one or two people answer a few dozen chats a day and you rarely message customers first. Add the WhatsApp Business API when you need to answer automatically, share chats across a team, or send updates to hundreds of customers. You don’t have to choose: the same number can run on both.
What the free app does well
- A business profile with your address, hours, catalogue and website.
- Quick replies, a greeting message and an away message.
- Labels to sort chats, and broadcast lists of up to 256 people.
- It’s free and it’s on the phone you already have.
Where the app runs out
- One phone. The account lives on one phone, with a few linked devices. Everyone who replies is logged in as the same “you”, with no way to assign a chat or see who answered.
- Broadcasts reach only people who saved your number. Anyone who hasn’t saved you never gets the message, and you can’t tell who that is.
- No real automation. Beyond the greeting, away message and quick replies, someone has to type every answer, book every slot and send every reminder.
- No connection to your other tools. Payments, Google Sheets, your website or booking system can’t send or receive WhatsApp messages through the app.
What the API adds
The API is WhatsApp’s official way for software to send and receive messages for a business. You use it through a provider such as GetSetSales, which gives you the screens on top:
- Automatic answers to common questions, any time of day, with appointments and payments inside the chat.
- A shared team inbox: several people answer from their own logins, chats are assigned, notes stay with the chat.
- Campaigns to opted-in customers, whether or not they saved your number, using templates Meta approves.
- Reminders and follow-ups that go out on their own and stop when the customer replies.
- Integrations: a payment on Razorpay sends a receipt on WhatsApp; a booking lands in your Google Sheet.
Side by side
| Business app | Business API (with a provider) | |
|---|---|---|
| Cost | Free | Meta’s per-message charge plus the provider’s fee |
| Who can reply | One account on a few devices | A whole team, each with their own login |
| Messaging many customers | Broadcast lists of 256, only to people who saved your number | Campaigns to opted-in customers, with approved templates |
| Automation | Greeting, away message, quick replies | Chatbots, bookings, payments, reminders, follow-ups |
| Reports | Basic message counts | Delivered, read and replied, per campaign |
| Connect other tools | No | Payments, Google Sheets, your own software |
What the API costs
Two parts. Meta charges per template message: in India about ₹0.8631 for marketing and ₹0.115 for utility (reminders, confirmations). Replies to customers who messaged you in the last 24 hours are free from Meta. Then the provider adds its fee. At GetSetSales that is ₹0.15 per template or automation run and ₹0.15 per conversation your bot or team answers, with no monthly plan and your first 100 free. A clinic sending 800 reminders a month pays well under ₹300 in all. The full breakdown, with worked examples, is in WhatsApp Business API pricing in India, and on our pricing page.
Keep the app and add the API on the same number
You no longer have to give up the app to use the API. With Meta’s coexistence option you connect the number you already use, and:
- you keep chatting from the WhatsApp Business app on your phone;
- your contacts and up to 6 months of chat history come across;
- customers see the same number, name and profile as before;
- automations, campaigns and the team inbox run alongside.
Your customers notice nothing, except that replies come faster.
When it’s time to switch
Any one of these is a good sign:
- You answer the same five questions many times a day.
- Enquiries arrive at night and are answered the next morning, if at all.
- Two or more people share one phone to reply.
- You chase payments or appointments one message at a time.
- You want to tell all your customers about something, and broadcast lists aren’t reaching them.
