Quick answer
The free WhatsApp Business app runs on one phone and suits a solo owner. The WhatsApp Business API, now the WhatsApp Business Platform, runs in the cloud and suits teams that need a shared inbox, automation, large broadcasts and integrations. If more than one person answers your number, or you want to automate, choose the Platform.
The WhatsApp Business app
- Free and quick to set up on one phone.
- Good for a single owner handling chats personally.
- Basic tools: quick replies, labels, catalog, away messages.
- Broadcast limited to 256 saved contacts, no real automation, one user.
The WhatsApp Business Platform (API)
- Cloud-based, so many agents share one number in a team inbox.
- Automation, chatbots, OTPs and scheduled notifications.
- Broadcast campaigns to large opted-in segments.
- Integrations with your store, CRM and backend, plus analytics.
How to choose
Pick the app if you are one person and your volume is low. Pick the Platform if any of these are true:
- More than one person needs to answer the same number.
- You want to automate replies, reminders or verification codes.
- You send campaigns beyond a few hundred contacts.
- You want WhatsApp connected to your other systems.
ZeniaOne runs on the WhatsApp Business Platform and adds the shared inbox, automation, commerce and analytics on top.
Frequently asked questions
Is the WhatsApp Business API better than the app?
It is not better for everyone. The app is simpler and free for one person. The API is better once you need a team, automation, large broadcasts or integrations.
Can I use both the app and the API?
Not on the same number at the same time. A number is on one or the other. Many businesses move the number from the app to the Platform as they grow.
Does the API cost more than the app?
Yes. The app is free; the Platform has a provider subscription and Meta's conversation fees. In return you get team, automation and scale.
