The market is increasingly driven by omnichannel engagement, WhatsApp Business APIs, conversational AI, automation, and cloud communication technologies.
What is CPaaS?
CPaaS (Communication Platform as a Service) is a cloud-based communication framework that enables businesses to integrate communication capabilities directly into applications, websites, CRMs, ERPs, and business workflows through APIs.
