Introduction
In today’s digital world, businesses need fast, reliable, and scalable communication systems to interact with customers. Whether it’s sending OTPs, notifications, or enabling voice calls, communication plays a critical role in user experience.
This is where CPaaS (Communications Platform as a Service) comes in.
CPaaS allows businesses and developers to integrate communication features like SMS, voice calls, video, and messaging directly into their applications using APIs—without building complex telecom infrastructure.
What is CPaaS?
CPaaS (Communications Platform as a Service) is a cloud-based solution that provides developers with APIs and tools to add real-time communication capabilities into websites, mobile apps, or software systems.
Instead of setting up servers, telecom networks, or messaging gateways, businesses can simply use CPaaS APIs to enable communication features instantly.
