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.
