# Overview

> A quick overview of SuprSend API reference.

SuprSend API enables you to add a powerful notification engine to your product. SuprSend offers a complete set of features that allow you to send notifications reliably and at scale, while ensuring a positive end-user experience, thus eliminating the need to build a notification service in-house. We offer backend SDKs in popular programming languages.
