Unity Asset Store (click to expand)

1. Add the OneSignal Unity SDK as an available asset to your account by clicking **Add to My Assets** from [our listing on the Unity Asset Store](https://assetstore.unity.com/packages/add-ons/services/billing/onesignal-sdk-193316). 2. Find the package waiting for you to download by clicking **Open in Unity** from that same page. This will open the Unity Editor and its Package Manager window. 3. On the SDK's listing in the Editor click the **Download** button. When it finishes click **Import**. ![onesignal unity sdk in my assets](https://github.com/OneSignal/OneSignal-Unity-SDK/raw/main/Documentation/asset_listing.png) 4. A prompt to import all of the files of the OneSignal Unity SDK will appear. Click **Import** to continue and compile the scripts into your project. 5. Navigate to **Window > OneSignal** (or follow the popup if upgrading) in the Unity Editor which will bring up a window with some final steps which need to be completed in order to finalize the installation. The most important of these steps is **Import OneSignal packages**. > *Depending on your project configuration and if you are upgrading from a previous version, some of these steps may already be marked as "completed"* ![sdk setup steps window](https://github.com/OneSignal/OneSignal-Unity-SDK/raw/main/Documentation/setup_window.png) 6. After importing the packages Unity will notify you that a new registry has been added and the **OneSignal SDK Setup** window will have refreshed with a few additional steps. Following these will finalize your installation of the OneSignal Unity SDK.

Unity Package Manager (click to expand)

1. From within the Unity Editor navigate to **Edit > Project Settings** and then to the **Package Manager** settings tab. ![unity registry manager](https://github.com/OneSignal/OneSignal-Unity-SDK/raw/main/Documentation/package_manager_tab.png) 2. Create a *New Scoped Registry* by entering ``` Name npmjs URL https://registry.npmjs.org Scope(s) com.onesignal ``` and click **Save**. 3. Open the **Window > Package Manager** and switch to **My Registries** via the **Packages:** dropdown menu. You will see all of the OneSignal Unity SDK packages available on which you can then click **Install** for the platforms you would like to include. Dependencies will be added automatically. 4. Once the packages have finished importing you will find a new menu under **Window > OneSignal**. Open it and you will find some final steps which need to be completed in order to finalize the installation. > *Depending on your project configuration and if you are upgrading from a previous version, some of these steps may already be marked as "completed"* ![my registries menu selection](https://github.com/OneSignal/OneSignal-Unity-SDK/raw/main/Documentation/registry_menu.png)

## Platform Configuration ### iOS After building in Unity and exporting the XCode project follow these steps: 1. To open your project ensure that you use the `.xcworkspace` file and not the `.xcodeproj` to open the project. 2. Click on the **Unity-iPhone** project and its similarly named target and select the **Signing & Capabilities** tab. 3. From here check **Automatically manage signing**, on the prompt click **Enable Automatic**, and select your **Team**. ![automatically manage signing](https://github.com/OneSignal/OneSignal-Unity-SDK/raw/main/Documentation/ios_auto_sign.png) 4. Scroll down to **App Groups** and click on the refresh button. > NOTE: You may have to press this a few times as it will ask you for each signing type. ![refresh app groups](https://github.com/OneSignal/OneSignal-Unity-SDK/raw/main/Documentation/ios_refresh_app_groups.png) 5. Repeat the same steps above but for the **OneSignalNotificationServiceExtension** target this time. ![extension signing and groups](https://github.com/OneSignal/OneSignal-Unity-SDK/raw/main/Documentation/ios_extension_sign_and_groups.png) 6. **App Groups** should now be provisioned for you going forward for your iOS bundle id, even on clean builds. ### Android Most of the Android setup was already handled during installation! The only thing remaining is to setup your own notification icons. You can do this be replacing the example icons located at `Assets/Plugins/Android/OneSignalConfig.plugin` with your own. There is a complete guide for this [in the plugin's README](https://github.com/OneSignal/OneSignal-Unity-SDK/blob/main/com.onesignal.unity.android/Editor/OneSignalConfig.plugin/README.md). See our [Customize Notification Icons](https://documentation.onesignal.com/docs/customize-notification-icons) page for additional details. ## Usage You can find a complete implementation in our included [example MonoBehaviour](https://github.com/OneSignal/OneSignal-Unity-SDK/raw/main/OneSignalExample/Assets/OneSignal/Example/OneSignalExampleBehaviour.cs). Additionally we have included a [sample scene](https://github.com/OneSignal/OneSignal-Unity-SDK/raw/main/OneSignalExample/Assets/OneSignal/Example/OneSignalExampleScene.unity) which you can run to test out the SDK. ### Initialization #### Prefab Located in the `com.onesignal.unity.core` package we've include a simple prefab which initializes OneSignal. You can easily find it using the Asset search bar to find `OneSignalController.prefab` and making sure to select **All** or **In Packages** for your search option. Drag the prefab into your very first scene, fill in the **App Id**, and you are immediately ready to go! #### Code To get started add the following code in an appropriate place such as the `Start` method of a `MonoBehaviour` early in your application's lifecycle. ```C# // Replace 'YOUR_ONESIGNAL_APP_ID' with your OneSignal App ID from app.onesignal.com OneSignal.Default.Initialize("YOUR_ONESIGNAL_APP_ID"); ``` You are now ready to start sending and receiving notifications and in-app messages.
