WhatsApp Business is a free application designed for small businesses and the self-employed, for business users such as small and medium-sized business owners, online retailers, local merchants, etc., who want to communicate with and serve their customers through WhatsApp.

It allows a single business to be used on up to 5 devices (1 primary device + 4 associated devices), making it ideal for small businesses that need multiple team members to collaborate on responding to customer messages.

What is the WhatsApp Business API?

The WhatsApp Business API (also known as the WhatsApp Business Platform), on the other hand, is built specifically for mid-sized and large organizations to support automated messaging at scale.

Unlike the WhatsApp Business app, which has no interface, businesses need to plug the API into their messaging system to enable:

• automated conversations and appointments 
• AI customer service bots 
• broadcast messaging 
• personalized Customer journey design

In addition, it has an auto-responder feature that allows merchants to pre-set an automatic greeting or reply to messages out of hours to ensure that customer queries are answered in a timely manner. Functionality tabs are also a feature of WhatsApp Business, which allows merchants to categorize and manage customers according to their status (e.g. New, Pending Response, Completed), making customer service more organized.

At the same time, it also provides message statistics to help merchants know whether the sent messages are read by customers, which provides a strong basis for the development of marketing strategies. It is worth mentioning that WhatsApp Business also has a catalog function, which allows merchants to display a catalog of their products or services on its page, so that customers can browse and learn about the product information directly in the chat interface, which further enhances the customer experience.

In Terms of Purpose of Use: 

WhatsApp Messenger mainly fulfills the daily communication needs between individual users, including sending messages, making voice and video calls, and sharing statuses.

WhatsApp Business, on the other hand, focuses more on providing a business communication platform for organizations to help them build a closer connection with their customers and improve customer service and marketing efficiency.

In terms of user interface although both apps are designed in a similar style, WhatsApp Business adds more business communication-related tabs and tools to its interface, providing businesses with a more convenient way to manage customer relationships and business communications.
