The difference at a glance
| WhatsApp Business app | WhatsApp Business API | |
|---|---|---|
| What it is | A free app on your phone | A connection to WhatsApp used through a platform or your own software |
| Cost | Free to use | Meta’s per-message fees, plus a platform fee if you use one |
| Who replies | Whoever holds the phone or a linked device | A whole team in a shared inbox, with assignment |
| Automation | Greeting, away message and quick replies | Flows, AI answers and booking, depending on the platform |
| Messaging many people | Broadcast lists, which only reach people who saved your number | Approved templates sent to opted-in contacts, within your messaging limit |
| Messaging first | You can start a chat from the phone | Only with an approved template |
| Verified badge | Meta Verified, a paid subscription where available | Official Business Account, by request |
Broadcast limits on the app are not well documented. Lists are widely reported to hold up to 256 contacts, so test what your own app allows before you plan around a number.
Stay on the app if this is you
- One or two people answer, and you get to every chat the same day.
- Few messages arrive after you close, or customers don’t mind waiting until morning.
- You don’t need reminders, follow-ups or campaigns to go out automatically.
- Most of your customers send voice notes. WapTalk plays them for your staff, but its AI can’t understand them yet, so a voice-heavy business gets less from the assistant today.
Paying for software you don’t need is a bad trade. The app is good, and it’s free.
Signs you’ve outgrown it
- Staff pass the phone around, or two people reply to the same customer because nobody can see who is handling what.
- Enquiries arrive after closing and are cold by the next morning. An away message tells them you’re closed but doesn’t answer the question.
- The same questions take up the day: fees, timings, location, availability.
- You want results you can measure, such as who enquired, who booked and which ad they came from.
- You want to reach existing customers at scale, including people who haven’t saved your number.
What the API really costs
There are two bills, and it helps to keep them separate.
- Meta’s fees, per delivered message: about ₹0.8631 for marketing and about ₹0.115 for utility, authentication and service messages, with the first 1,000 service messages per number free each month (October 2026, before 18% GST). See the full rates and calculator.
- The platform’s fee for the inbox and automation. Some platforms also charge above Meta’s rate per message, so ask. WapTalk plans start at ₹2,499/month + GST, with the AI included and 0% markup on Meta’s fees. See how that compares with Wati.
You can use the Cloud API without a platform, and Meta’s side costs the same. But you then need a developer to build and run everything your staff would use.
What changes when you move
- Your number. A number on the app must normally be moved off it before the API can use it. Meta’s coexistence option lets you keep the app alongside the API, but it isn’t offered for every number, so check before you plan on it. A new number avoids the question.
- The 24-hour rule. You can send normal replies for 24 hours after a customer’s last message. After that, you need an approved template.
- Messaging limits. A new account can send to 250 unique people a day outside those 24-hour windows. Verifying your business is one route to 2,000.
- Business paperwork. Have your GST or Udyam registration ready, since Meta may ask for documents to verify the business. The setup guide covers the steps.
WapTalk’s setup is guided for now, because our self-serve Connect WhatsApp button is waiting on Meta’s App Review. You can talk to us before you change anything on your number.
