A customer signs up for your application and instantly receives an OTP for verification. They later receive an order confirmation via SMS, connect with customer support through voice, and join a video consultation—all within the same platform. To the customer, it feels like a seamless experience. Behind the scenes, however, delivering these real-time communication services requires a reliable and scalable infrastructure.

Building and maintaining that infrastructure from scratch demands significant time, resources, and technical expertise. This is where Twilio simplifies the process by providing cloud-based communication APIs that enable businesses to integrate voice, messaging, video, email, and authentication into their applications without managing complex telecom infrastructure.

Why Twilio

Twilio is a cloud Communications Platform as a Service (CPaaS) that enables developers to receive calls, messaging, video, and authentication in applications via a single web service API. It’s built on WebRTC to leverage its features when building software applications without creating backend infrastructure from scratch. Also, Twilio handles server scaling and even provides STUN/TURN infrastructure so your team never has to manage it directly.
