# SMPP API

### Overview

SMPP, or [Short Message Peer-to-Peer](https://en.wikipedia.org/wiki/Short_Message_Peer-to-Peer), is a widely accepted protocol in the telecommunications industry. It's used to facilitate the exchange of SMS messages between Short Message Service Centers (SMSCs) and External Short Messaging Entities (ESMEs).

This guide assumes you have a foundational understanding of the SMPP protocol and can confidently set up your own SMPP client software. \

Let's build on that and explore more.
