Short answer
The WhatsApp Business App is free and works for one business on a few phones. The WhatsApp Business API (Meta’s Business Platform) is for businesses that need many team members on one number, automated replies, order updates and integration with their CRM or software. Since 1 July 2025 Meta charges per message, by message category.
App or API: what is the difference?
| Compared on | WhatsApp Business App | WhatsApp Business API |
|---|---|---|
| Cost | Free | Per message, set by Meta |
| Team | A few linked devices | Many agents on one number |
| Automation | Basic quick replies | Automated flows, bots and AI |
| Integration | None | Connects to CRM, ERP and your software |
| Bulk updates | Limited broadcast lists | Approved templates to opted-in customers |
How does WhatsApp API pricing work?
Since 1 July 2025, Meta charges per message instead of per conversation. Template messages are grouped into categories: marketing, utility (such as order updates) and authentication (such as one-time passwords). Replies to a customer within the customer service window are free, and utility templates sent inside that window are not charged. Rates differ by country and change from time to time, so always check Meta’s current rate card.
What do you need to get started?
- A Meta Business account for your company, and a phone number not already used on WhatsApp.
- Customers’ permission (opt-in) before you message them first.
- Approved message templates for anything you send outside the customer service window.
- Software that connects the API to your team and your systems.

Frequently asked questions
Is the WhatsApp Business API free?
No. The free product is the WhatsApp Business App. The API is charged per message by Meta, with free replies inside the customer service window.
Can I send bulk messages with the API?
You can send approved template messages to customers who have opted in. Messaging people who did not agree risks your number being restricted.
Can the WhatsApp API connect to my CRM?
Yes. That is one of its main advantages: every message and order update can be logged against the customer in your CRM or software.
