The SDK package contains a special file, ‘ads.txt’. This file is used to declare the authorized advertising systems.
Copy this file in the same location as that of the game.
In case of mobile games, file is named as ‘app-ads.txt’. As in the case of desktop applications, copy this file to the same location as that of the game. You must also enter this URL at the app store where your mobile game is sold.
Note: There can only be one ads.txt and app-ads.txt file per system. In case of multiple games, this file is shared across all the games.
