This restricts ads to the defined type, potentially resulting in no fill. Valid `ft_ctype` values include `html5`, `image_app_install`, `video_app_install`, and others, each with supported formats (e.g., Banner, Interstitial). This parameter only works in test mode and impacts only Google ads, not third-party ads from mediated sources.\n"]]
