SMS API DEFINITION

What is SMS API

An SMS API is a set of programming protocols and tools for building software and applications. It allows businesses to integrate SMS functionality directly into their existing systems, such as CRMs, marketing automation platforms, or even proprietary software. This enables the sending and receiving of SMS messages on a large scale, automating communication processes, and enhancing customer engagement.
