WhatsApp app vs. Business API, what is the difference?
The free WhatsApp Business App is suited to individuals and very small businesses. It runs on a single device, has no automation and no API integration.
The WhatsApp Business API is built for professional businesses. It enables automation, CRM integration, AI chatbots, broadcasts and multi-agent access. That is exactly what powers Leadmatix.
- Multiple team members work at the same time
- AI automation and chatbots supported
- CRM integration with contact management
- Send broadcasts and newsletters
- Officially supported by Meta

Frequently asked questions about the WhatsApp Business API
Can I keep using my existing WhatsApp Business number?
Yes, you can migrate an existing number. It has to be logged out of the regular WhatsApp app first. Leadmatix guides you through the migration.
How much does the WhatsApp Business API cost?
Meta charges per conversation (24-hour window). The first 1,000 service conversations per month are free. Leadmatix has transparent pricing with no hidden markup.
How long does Meta verification take?
Business verification at Meta typically takes 1 to 3 business days. With complete documents it is often faster.
Is the WhatsApp Business API GDPR-compliant?
Meta provides a Data Processing Agreement (DPA). Leadmatix stores conversation data on European servers and is fully GDPR-compliant.
These API setup mistakes cost you time
API setup is technically manageable, but common pitfalls slow many companies down. With Leadmatix you avoid all of them from the start.
- Number is still active in the WhatsApp app, migrate it first

- Missing two-factor authentication on the Meta account
With Leadmatix: no coding required
