WhatsApp gives you two business-related possibilities. Which one is best for you will depend on how big your firm is. Small enterprises are the target market for the WhatsApp Business App API. A WhatsApp Business account API can be made without cost. Basic features like automated messages, fast replies, contact tagging, and a business profile are included. The WhatsApp Business App API only permits one person to manage an account, making it unsuitable for big, quickly expanding companies. The purpose of the tool was to connect small business owners with customers. Bigger companies can use WhatsApp API to deliver notifications to clients and provide excellent customer support.
