# Accent SMS API Guide

## Introduction

This document describes use of the Accent Public SMS API. The API seeks to allow users to send outbound SMS messages using Accent DIDs as well as create routes for inbound messages to be delivered.

## Authentication

The Accent Public SMS API uses 40-character API keys to authenticate all responses. You can retrieve your SMS API Key from the Accent Support Team, which can be contacted via our [Support Page](https://www.accentvoiceone.com/tech-support).

It is necessary to provide your 40-character API key as a parameter of the JSON payload used in all `POST` and `DELETE` requests. For `GET` requests, it may be provided as a GET parameter in the URL.

## API Request URLs <a href="#api-request-urls" id="api-request-urls"></a>

All API requests will be sent to URLs with the following structure:

`https://sms.accentvoice.com/api/v2/<DID Number>/`

Simply replace `<DID Number>` with an authorized 11-digit DID number to get the base for the request URL.
