WhatsApp Business app vs WhatsApp Business Platform (API)
The two products Meta calls "WhatsApp Business", what each one can and cannot do, and how to tell which one your business actually needs.
On this page
Meta ships two different things under the name "WhatsApp Business", and choosing between them is the first decision any business makes on the channel. They are not tiers of the same product — they are different products with different limits, and one of them is not an app at all.
The short version
| WhatsApp Business app | WhatsApp Business Platform (the API) | |
|---|---|---|
| What it is | A phone app, free from the app store | An interface other software connects to |
| Where you answer | One phone (plus linked devices) | Any number of people, in a shared inbox |
| Cost | Free | Per message, plus whatever the platform charges |
| Automation | Away messages, quick replies, simple greeting | Anything the connected platform supports |
| Broadcast | Up to 256 saved contacts at a time, manual | Approved templates, to a list, with delivery reporting |
| Integrations | None | Anything that can call an API |
| Catalog & payments | Basic catalog | Catalog, payments, order status |
When the app is the right answer
Honestly: often. A one-person business, or a shop where the same person always answers, is well served by the free app. It costs nothing, it needs no setup, and every message is free.
Stay on the app while all of these are true:
- One person answers, and they always have the phone.
- Nobody needs to see the history but them.
- You are not sending scheduled or bulk messages beyond an occasional broadcast list.
- Nothing else needs to know about the conversation — no bookings system, no shop, no CRM.
When you have outgrown it
The app stops working the day any of these becomes true, and each fails in its own way:
- A second person needs to answer. The app is bound to a phone. Sharing the phone is the workaround, and it collapses the moment two people are working at once, or one is on leave and the other cannot see what was said.
- You need to know what happened. There is no reporting: no response times, no volumes, no "how many people asked about that this month".
- Someone needs reminding. Appointment reminders, order updates and delivery notices all mean sending first, at a time you choose, to people whose 24-hour window is closed — which needs approved templates.
- Another system holds the truth. Bookings, orders and stock live somewhere else, and copying between them by hand is where the errors come from.
- You want an assistant to answer the routine questions. Nothing on the app can do this.
The API is not something you use directly
This trips people up. The WhatsApp Business Platform has no screen. It is an interface that software connects to — you use it through a platform like Juno, which provides the inbox, the automation, the templates and the reporting. "Getting the API" and "choosing a platform" are the same decision.
That also means the per-message cost Meta charges is separate from what the platform charges. See pricing.
You may not have to choose
The third option is coexistence: one number running in the owner's WhatsApp Business app and on the API at the same time. The phone keeps working, the team gets a shared inbox, and the existing chat history is imported once.
This is what most small businesses actually want, and it is what Juno's sign-up requests by default. It is worth knowing before you start, because the choice is made during sign-up and cannot be changed afterwards — standard API onboarding registers the number exclusively and signs it out of the app, with no undo.
What is not a difference
A few things people expect to differ, and do not:
- The customer sees the same WhatsApp. There is no "business API" experience on their end.
- Your number is your number. Both use a real phone number, and both can use a landline.
- The green tick is separate from both. See business verification.
