WhatsApp Business API is different from the free to download WhatsApp Business App. To know which one is better suited to your business, check out the key differences highlighted below. WhatsApp Business API is a solution for large and medium enterprises which allows them to communicate with their customers at scale through an interface. It can be used throughout the customer journey from sign up and verification to sending notifications and reminders, and lastly two-way customer service. This needs to be aligned to WhatsApp’s commercial policy and terms and conditions. When looking to integrate WhatsApp Business API as a messaging and customer service solution, it is important to do it through an authorized WhatsApp Business Solution provider, such as Infobip. WhatsApp Business App is a free to download mobile application for small business owners that allows them to communicate with customers over WhatsApp on behalf of the business. Unlike WhatsApp Business API, it has limited scalability and only up to 5 employees can manage the account through one phone. The app provides limited customer service and aims to enable businesses to show their products and services, and to respond to customer messages.
