# React Native Expo Plugin

## Step 1: Prerequisites

### Android Requirements

All apps must have a Firebase project and matching credentials to capture subscriptions and send notifications. Follow the link below to create a Firebase project for your app and add the credentials to our platform.

Before you can integrate the SDK with your app the following requirements must be met:

* Android device or emulator running API 19+ (Android 4.4) with Google Play Store Services installed.
* An app that uses [<mark style="color:blue;">Jetpack (AndroidX)</mark>](https://developer.android.com/jetpack/androidx/migrate)
* Firebase Sender ID and Server API Key or Service Account. If you do not already have these follow [<mark style="color:blue;">our documentation</mark>](https://documentation.pushly.com/integration/implementation-steps/android/firebase-app-setup) to generate them.
* SDK Key: Obtained from the Pushly Platform in the `Domain Settings` page under the `Details` > `Domain Information` section.

### iOS Requirements

In order to begin subscribing users to notifications you must have either a P8 Key (recommended) or a P12 Certificate; Either of these can be generated via the Apple Developers portal.

* An [<mark style="color:blue;">Apple Developer Account</mark>](https://developer.apple.com/account/) that has Admin privileges
* Your application's App Bundle ID (e.g., `com.pushly.example`)
* An iOS application or XCode project with the Push Notifications capability added

In addition to the above the following requirements must be met:

* An iOS 11+ device (iPhone, iPad, or iPod Touch) to develop and test on.
  * **Note:** The XCode Simulator does not support remote push notifications. A physical device must be used.
* A Mac OS device with XCode 13+ installed.
* An iOS P12 Push Certificate or P8 Key. If you do not already have these follow [<mark style="color:blue;">our documentation</mark>](https://documentation.pushly.com/integration/implementation-steps/apple-ios/p8-key-or-p12-cert-setup) to generate them.
* SDK Key: Obtained from the Pushly Platform in the `Domain Settings` page under the `Details` > `Domain Information` section.
