Almost every business we talk to already uses WhatsApp. The question is not whether to use it, but which version. The free WhatsApp Business app and the WhatsApp Business Platform (usually called the API) look similar to customers, but behind the scenes they are very different tools.
Key takeaways
- The app is built for one phone and manual replies. The API is built for teams, automation and integration.
- With the API, Meta charges per conversation category; software platforms charge separately.
- Switch when more than one person needs to reply, or when you want automated flows, broadcasts to opted-in customers or system integrations.
What the WhatsApp Business app does well
The app is free, quick to set up and perfect for a shop owner who personally replies to customers. You get a business profile, catalogue, quick replies, labels and simple away messages. For a single person handling a few dozen chats a day, it is often enough.
The limits show up as soon as you grow. The number is tied to one primary device (with a small number of linked devices), there is no proper assignment of chats to staff, no audit trail of who replied what, and automation is limited to greeting and away messages.
What changes with the API
The WhatsApp Business Platform is not an app you download. You connect your number to Meta's Cloud API through a platform (for example WaZappy), and your team uses that platform's dashboard.
| Need | Business app | Business API |
|---|---|---|
| Multiple agents on one number | Limited linked devices | Yes, with roles and assignment |
| Chatbots and flows | Greeting/away messages only | Full no-code flows, AI replies |
| Messages after 24 hours | Manual | Approved templates |
| Integration with CRM/ERP | No | Yes, via API and webhooks |
| Cost | Free | Meta conversation charges + software plan |
How the 24-hour window works
When a customer messages you, a 24-hour customer service window opens. Inside it you can reply freely. Outside it, you must use a message template that Meta has approved — for example an order update, an appointment reminder or an offer to customers who opted in. This is the single most important rule to understand before moving to the API.
What does it cost?
Meta charges for conversations based on category (marketing, utility, authentication, service) and the customer's country. These charges are billed by Meta to the payment method on your Meta Business account. The platform you use charges separately for its software. On WaZappy, for example, Meta charges are passed through with zero markup and a free plan is available to start.
What you need to get started
- A Meta Business account (Business Manager).
- A phone number that is not active on the WhatsApp app — or one you are ready to move.
- Business details for verification, such as GST or other registration documents.
- A Visa or Mastercard card for Meta's billing.
When should you switch?
From our experience setting up WhatsApp for businesses, these are the clearest signals:
- Two or more people need to answer customers from the same number.
- The same ten questions take up most of the day.
- You want to send order, payment or appointment updates automatically.
- Leads from ads or the website need to be tracked and followed up.
If none of these apply yet, stay with the app — it is a great tool. If two or more do, the API will save time within the first month.
Frequently asked questions
Can I use the same number on the app and the API?
Not at the same time. A number connected to the API cannot be used in the regular WhatsApp app.
Will I get the green tick?
The verified badge is granted by Meta based on notability and is not guaranteed by any provider. Business verification and display-name approval are separate and required for the API.
