# 17.3 Code Setup for IAP

{% hint style="info" %}
Make sure you have completed all of the previous steps of 17, 17.1 & 17.2.

You will get an **iap.zip** file from us in your email after contacting us with your purchase code. Unzip it and you will get a folder named **IAP**. Copy this folder and paste this folder into the **quiz\_app/lib** folder.

Open the app source code in your IDE and open the **lib/IAP/iap\_config.dart** file.

Now add your IAP **Product IDs** here separated with commas as shown in the picture below.

That's it. Your IAP setup is completed. Now, you can test the app and the IAP products and publish your app in production by uploading a new version.

To test the In-App Purchases feature, use a real Android or iOS phone. Emulator/Simulator doesn't support this.
