Overview
We offer a number of different APIs and libraries that make it easy for you to use our SMS services globally, to send and receive messages.
The different SMS APIs
REST
The easiest and most feature-rich API we offer. It allows for single messages, scheduled batch sending, message templates and more. You can also use our server-side libraries if you like to work natively in your programming language of choice.
SMPP
SMPP interfaces for full control and low latency.
