WhatsApp Business API setup is the only way to scale your team.
Many businesses get stuck. They use the free app. It works for one person. But it fails for teams. You cannot scale with a single phone. You need a server-based solution. That is why you need this WhatsApp Business API Guide 2026.
WhatsApp App vs. API: Which Do You Need?
You need the API for teams. The free app lives on one phone. It connects to 10 web devices. That is it. The API lives on a cloud server. It allows unlimited users. It connects entire sales teams using a WhatsApp shared team inbox.

This feature is not available everywhere. If you are in a restricted region like the EU (European Union), the old rule applies. You must delete the app account first. Always check your local rules before you start.
