- About us
We’re a technology company ourselves, with a dedicated in-house development team, so you can be assured that our SMS API is easy to use, yet offers sophisticated functionality. It’s constantly evolving with help from our developer community.
Our SMS API is practical, straightforward and supported with detailed documentation including example code to get you started quickly.
On our website you’ll find sample code, documentation, a support section. But if you’d rather speak to someone instead, just drop us an email email@example.com.
It’s quick and easy to integrate with our SMS gateway, no matter which programming language you use.
Built on the ReSTful API (Representational State Transfer)
