> Register your devices used for testing Unity Ads integrations in unpublished apps on the Unity Ads Monetization dashboard to avoid being flagged for fraud.

Prior to publishing your project, you must register any devices that you use for testing a Unity Ads integration on the [Unity Ads Monetization dashboard](https://cloud.unity.com/monetization) to avoid being flagged for fraud.

To manage registered test devices across all projects for your Organization, complete the following steps:

1. Go to the **Monetization** menu, then select **Settings** > **Test devices**.
2. Select the app you want to create a test device for.
3. Select **Create test device** to register a new Android or iOS test device, then enter the device platform, device name, and advertising ID.
4. Edit the **Test mode** field,  enable **Override client test mode**, then select **Force test mode ON for all devices** to use test ads for all devices.
