WhatsApp Business API: What is a Customer Care Window?
With the WhatsApp Business solution, there are two ways to chat with your customer. Once a customer opts-in to receiving messages from your business, you can initiate a conversation by sending notifications via so-called Messages Templates, or the customer can initiate a conversation with your business. Whenever your customer contacts or replies to you, a customer care window is opened. This customer care window creates more opportunities for you to benefit from the WhatsApp Business solution.
