The free WhatsApp Business app works for a shop owner on one phone. The API is for teams, automation and scale. Here is how to choose.
Both products let a business talk to customers on WhatsApp, but they are built for very different sizes of business. Picking the wrong one either costs you money you don't need to spend or caps your growth.
The WhatsApp Business app
A free app you install on a phone. Good for small businesses with one or two people answering chats.
- Free to use
- Business profile, catalogue, quick replies and labels
- Broadcast lists that only reach people who saved your number
- Works on one phone plus a few linked devices
- No real automation, no CRM connection, no reporting
The WhatsApp Business API (Business Platform)
An interface for software, not an app. You use it through a provider's dashboard or your own system.
- Many agents can answer from one number through a shared inbox
- Chatbots, automated replies and integration with your CRM or store
- Approved template messages to opted-in customers at scale, even if they haven't saved your number
- Delivery and read reports, webhooks and analytics
- Paid per delivered template message, by category and country

One thing to know before switching
A number used on the API cannot be used in the regular WhatsApp or WhatsApp Business app at the same time. Plan the move, or use a new number for the API.
TextNSMS provides the official WhatsApp Business API with a team inbox, chatbots and webhooks, and bulk WhatsApp campaigns with approved templates.
Frequently asked questions
Is the WhatsApp Business API free?
No. Meta charges per delivered template message, by category and country. Replies within the 24-hour customer service window are free under Meta's current pricing.
Can I keep using the WhatsApp Business app after moving to the API?
Not on the same number at the same time. Many businesses move their main number to the API and handle all chats from the shared inbox.
