Google Mobile Ads SDK provides an API that lets you specify a creative type for test queries. When the parameter is set, only creatives of the specified type are retrieved and rendered. ## Usage To specify a creative type, include the `ft_ctype` parameter in an extras object and pass it to the ad request. This may restrict which ads are available and result in no fill. > [!NOTE] > **Note:** The `ft_ctype` parameter only works in [Test Mode](https://developers.google.com/admob/ios/test-ads.md.txt#enable_test_devices). ### Swift ```swift let extras = Extras() extras.additionalParameters = ["ft_ctype": "video_app_install"] let request = Request() request.register(extras) ``` ### Objective-C ```objective-c GADExtras *extras = [[GADExtras alloc] init]; extras.additionalParameters = @{@"ft_ctype" : @"video_app_install"}; GADRequest *request = [GADRequest request]; [request registerAdNetworkExtras:extras]; ``` The following table lists the valid values for `ft_ctype`: | Creative Type | ft_ctype | Format | |---|---|---| | HTML5 | html5 | Banner, Interstitial, Rewarded | | App install image | image_app_install | Banner, Native, Interstitial, Rewarded | | Display image | image_display | Banner, Interstitial | | Display partial slot | partial_slot | Banner, Native, Interstitial | | App install text | text_app_install | Banner, Native, Interstitial | | Display text | text_display | Banner, Native, Interstitial | | Trueview | trueview | Interstitial, Rewarded | | App install video | video_app_install | Banner, Native, Interstitial, Rewarded | This feature impacts Google ads only. If your ad unit enables [mediation](https://developers.google.com/admob/ios/mediation.md.txt), ads returned from third-party ad sources don't respect the `ft_ctype` parameter. We recommend testing with an ad unit that doesn't have mediation enabled.
