The WhatsApp Business Platform (often called the WhatsApp Business API) is Meta's official way for businesses to send and receive WhatsApp messages from software instead of a phone.
App vs. platform
- The WhatsApp Business app runs on one phone (plus linked devices).
- The platform is used through software like Procellari, so a whole team can work from one number.
- With coexistence, a number can stay on the app while also being connected to the platform.
What you need
- A Meta business portfolio (verification raises your limits).
- A phone number you control.
- A display name that matches your business.
- A platform like Procellari to send, receive and automate.
Templates and the 24-hour window
You can reply freely for 24 hours after a customer messages you. To start a conversation — or reply after 24 hours — you send a message template that Meta has approved.
