The WhatsApp Business Platform — often called the WhatsApp Business API or Cloud API — is the official way for companies to send and receive WhatsApp messages at scale. Unlike the free WhatsApp Business app (built for one small business on one phone), the API supports automation, multiple agents, broadcasts and integration with your systems.
App vs. API: the key difference
The app is a phone-bound inbox. The API is infrastructure: it has no built-in interface, which is exactly why it can power shared inboxes, chatbots, notifications and CRM integrations. You access it through a Business Solution Provider (BSP) or Meta’s Cloud API.
What you can do with the API
- Let a whole team work from one official number
- Send transactional notifications (OTP, orders, bookings, payments)
- Run compliant broadcast campaigns with opt-in
- Deploy AI assistants and chatbots
- Connect WhatsApp to your CRM, ERP and other tools
When do you need it?
If you have message volume, a team, or systems you want WhatsApp connected to, you have outgrown the app. That is where Whatsoza comes in: we set it up, integrate it and run it for you.
