It also allows real-time international audio and video calls for one-to-one and group. Moreover, you can even share status updates. Well, it has a payment feature, too. All in all, it has brought people closer with just a tap on their phones.

They keep on adding new features for your needs and convenience.

What is the WhatsApp Business App?

To solve this and other limitations, WhatsApp Business API is the answer.
