The WhatsApp Business API is a tool that allows businesses to communicate with customers through the WhatsApp messaging app. The API enables businesses to send and receive messages, track message delivery and read receipts, automate responses and create chatbots, and more. Businesses can use the API to send notifications, confirmations, alerts, and other types of information to customers, making it a powerful tool for customer engagement and support. To use the API, businesses must be approved by WhatsApp and must have a verified business account. The API requires a secure connection and can be integrated into a company’s existing systems and workflows.
