According to a report, the global telecom API market revenue is projected to reach USD 1,459.5 billion by 2033. Communication features like messaging, voice calls, video calls and emails have become indispensable. 

These features enhance user experience, build engagement, and provide seamless interactions. However, building these features from scratch can be resource-intensive and time-consuming. This is where communication APIs come into play, offering pre-built, customizable features that you can integrate into your applications efficiently.

What is a Communication API?

‍

 A communication API focuses specifically on enabling pre-built communication features like messaging, voice calls, video chats, email and SMS APIs. 

Communication APIs enable seamless integration between a company’s systems and other business tools like CRMs, IoT devices or e-commerce platforms. They establish a secure and reliable framework for exchanging data across systems, eliminating the risks of manual errors and potential tampering.

These APIs leverage various technologies, such as

• REST (Representational State Transfer)
• SOAP (Simple Object Access Protocol)
• gRPC (Google Remote Procedure Call)
