WhatsApp Business is a standalone service that small, medium, and large businesses can use.

Interface and Design

After connecting, the business receives a confirmed profile with the coveted green checkmark. Unlike a business application, the API version provides a guarantee of an alphabetic name and the ability to be used by several employees, because Watsap Business is on a computer and is linked to CRM. 

The main feature of WABA is the 24-hour rule. What does it mean? The first message to a business customer will be charged. But if the client responds within 24 hours, then the next message from the company (also within 24 hours) will be free. During this period, the company can correspond freely and free of charge with the client. After each message is sent in time, the dialog box is restarted. But after the 24-hour window, the company can only send generic paid responses. 

Features and Usability

The WhatsApp Business API is intended for large companies that receive a large number of requests, and operators process requests from different channels (other messengers, chat on the website, social networks, and so on). Messages for mailing lists are moderated and are called HSM messages. 

Please note that the philosophy of WhatsApp is the company to use, not used to the company. To receive any messages from you, the user must explicitly agree to receive notifications on WhatsApp.

Security

Since correspondence is very personal, your privacy and security are very important to WhatsApp. Your messages and calls are automatically protected with end-to-end encryption, so no one, including WhatsApp, can read or listen to them. The company has also developed additional features to keep you safe on WhatsApp. 

The main problem is the risk of getting banned for mailing. You can be blocked for 5 or more identical messages to new customers. You can also get banned for 20-30 messages to regular customers.
