In today’s mobile-first world, customers prefer fast, personalized, and convenient communication. With over 2 billion active users, WhatsApp has become one of the most important platforms for brands to connect with their audience. While the WhatsApp Business App is designed for small businesses, companies that want to scale require a more robust solution. This is where the WhatsApp Business API comes into play.
By offering automation, multi-agent access, chatbot integration, and advanced marketing capabilities, the API is revolutionizing how businesses manage global communication.
What is WhatsApp Business API?
The WhatsApp Business API is an advanced communication interface designed for medium and large businesses. Unlike the regular Business App, which runs on a single device, the API connects directly to a company’s CRM, helpdesk software, or marketing platforms.
