# Introduction

{% hint style="success" %}
This document will help you through MPush API integration.
{% endhint %}

### Getting Started

MPush follows a **Publish/Subscribe** model based on topics to determine which devices receive a notification.

Devices can subscribe to one or more topics. Your backend can then send push notifications to specific topics, and only devices subscribed to at least one of the targeted topics will receive the message.

The MPush API is built on REST principles and uses JSON for both requests and responses. Errors are communicated using standard HTTP status codes and include detailed information in the JSON response body.

To simplify mobile integration, open-source SDKs are available for both [iOS](https://github.com/Mumble-SRL/MPush-iOS) and [Android](https://github.com/Mumble-SRL/MPush-Android). Refer to the iOS and Android documentation for implementation details.

Before getting started, make sure you have an API authentication token. It is required for every API call, as described in [Authentication](/api/authentication.md). To request a token, please send an email [here](mailto:developers@shoppy.is?subject=MPush%20Auth%20Token).
