Step 2: Set up a Firebase Cloud Messaging client app with Unity

If you do not have Firebase project

If you do not have Firebase project yet, you will have to set it up.
We suggest following official setup guide .

If you already have Firebase project

If you already have Firebase project, you have to add Firebase configuration files to your Unity app:

  • For iOS — GoogleService-Info.plist.
  • For Android — google-services.json.
    They can be placed anywhere in Assets folder.

Also you have to download Firebase Unity SDK from Add Unity SDKs section in official setup guide page or by a direct link .

After this return to Unity and follow these steps:

  1. Click Assets → Import package → Custom package...
  2. Pick Firebase Unity SDK which you downloaded
  3. Choose FirebaseMessaging.unitypackage and import all assets from this package.

Initialization of RetenoSDK

We highly recommend to initialize RetenoSDK as soon as possible after the start of your application.
To initialize the SDK you need to retrieve an access key from Reteno admin panel.
In your C# script call RetenoSDK.Initialize(...) and pass the key as the parameter:


The Core RetenoSDK setup is done, now you can navigate to specific platform setup:

  • iOS (Not available in current RetenoSDK version)
  • Android
