WhatsApp Cloud API

Meta's official Cloud API: Integrate WhatsApp messaging directly into your business systems (CRM, marketing) to communicate with thousands of customers at enterprise scale.

This is the cloud-hosted version of the WhatsApp Business Platform, managed directly by Meta. It eliminates the need for costly server infrastructure and third-party Business Solution Providers (BSPs) for hosting, offering a direct, quick-access solution. Businesses can build custom experiences, automate customer interactions with bots, and send up to 250 messages per second. Meta handles all maintenance, security updates, and automatic scaling to meet high-volume demands, ensuring a robust, cost-effective, and secure communication channel for any medium to large enterprise.
