What is an SMS API?

An SMS API (Application Programming Interface) is a set of protocols and tools that allows software applications to communicate with and send short message service (SMS) messages through a telecommunication network. In the context of SMS APIs, the telecommunication network is often the infrastructure provided by a mobile carrier or a cloud-based communication platform.

How does an SMS API work?

An SMS API (Short Message Service Application Programming Interface) enables software applications to send and receive SMS messages through a telecommunication network. Developers integrate the SMS API into their applications by incorporating the API's code or library into their software. This integration allows the application to communicate with the SMS service provider.
