In this session, we will understand how to set up WhatsApp Business API in a proper and systematic way. Earlier, we discussed what WhatsApp Business API is. In simple words, WhatsApp Business API works like a chatbot system that helps businesses automate communication with customers. It is especially useful for businesses running ads on Facebook and Instagram and receiving a high number of inquiries daily.
Why WhatsApp Business API is Required
Handling High Daily Inquiries
If you are running ads on Facebook and Instagram and receiving around 30–40 inquiries daily, replying to all of them manually becomes very difficult.
Many times, customers send messages late at night, such as:
- 12:00 AM
- 1:00 AM
In such situations, it is not possible to reply manually every time. WhatsApp Business API allows you to send automatic replies to customers.
This is one major reason why WhatsApp Business API is used.
Limitation of Normal WhatsApp and WhatsApp Business
Another major reason for using WhatsApp API is bulk messaging.
You cannot send bulk messages using:
- Normal WhatsApp
- WhatsApp Business
If you try to send bulk messages from these apps, your number can get banned.
WhatsApp Business API is specifically designed for bulk messaging.
Bulk Messaging Capability
Using WhatsApp Business API, you can send messages to:
- 5,000 users
- 10,000 users
- Even 1 lakh users
This is completely allowed and safe when done through WhatsApp Business API.
Verified Business Profile Advantage
With WhatsApp Business API:
- Your business profile appears as verified
- Your business name is shown by default
Even if the user has not saved your mobile number, your business name will still be visible when you message them.
Selling Products and Services Using WhatsApp Business API
WhatsApp Business API can also be used for:
- Selling products online
- Selling services online
It allows automatic communication with customers and can even collect payments through chatbot flows.
Mandatory Requirement Before WhatsApp Business API Setup
