# 4. Push Notification Setup

We have used OneSignal for push notifications. To set up OneSignal Push Notification Service to the app, you need an **App ID** from OneSignal. Follow the steps below:

* Go to [onesignal.com](https://onesignal.com/) and create an account and create a project by clicking on the new app/website button.

* Enter your **app name** and then select **Google Android**.
* And then you need a **Web API Key** and a **Sender ID**.

* You will get them from your firebase project. Go to your firebase project > project settings > cloud messaging and copy them and input both **Server Key** and **Sender ID** in the Onesignal and save them and complete the setup.

* You will get an **App ID** from Onesignal. Copy that App ID and go to the **lib/configs/config.dart** file and replace the Onesignal App ID.&#x20;

That’s it. Your OneSignal Push Notification Setup is complete.
