This parameter, added to an extras object in the ad request, restricts served ads to the specified type (e.g., `video_app_install`). Valid `ft_ctype` values include `html5`, `image_app_install`, `text_display`, etc. This only functions in Test Mode and doesn't affect reservation inventory or third-party mediation ads. Testing is recommended with a backfill-only ad unit without mediation enabled.\n"],null,["Select platform: [Android](/ad-manager/mobile-ads-sdk/android/test-creative-types \"View this page for the Android platform docs.\") [iOS](/ad-manager/mobile-ads-sdk/ios/test-creative-types \"View this page for the iOS platform docs.\")\n\n\u003cbr /\u003e\n\nGoogle Mobile Ads SDK provides an API that lets you specify a creative type\nfor test queries. When the parameter is set, only creatives of the specified\ntype are retrieved and rendered.\n| **Important:** This feature doesn't apply to reservation inventory, which may still serve if not explicitly disabled for the specified slot. We recommend that you test with a backfill-only ad unit.\n\nUsage\n\nTo specify a creative type, include the `ft_ctype` parameter in an extras object\nand pass it to the ad request. This may restrict which ads are available and\nresult in no fill.\n**Note:** The `ft_ctype` parameter only works in [Test Mode](/ad-manager/mobile-ads-sdk/android/test-ads#enable_test_devices). \n\nKotlin \n\n val extras = Bundle()\n extras.putString(\"ft_ctype\", \"video_app_install\")\n\n val request = AdManagerAdRequest\n .Builder()\n .addNetworkExtrasBundle(AdMobAdapter::class.java, extras)\n .build()\n\nJava \n\n Bundle extras = new Bundle();\n extras.putString(\"ft_ctype\", \"video_app_install\");\n\n AdManagerAdRequest request = new AdManagerAdRequest\n .Builder()\n .addNetworkExtrasBundle(AdMobAdapter.class, extras)\n .build();\n\nThe following table lists the valid values for `ft_ctype`:\n\n| Creative Type | ft_ctype | Format |\n|----------------------|-------------------|----------------------------------------|\n| HTML5 | html5 | Banner, Interstitial, Rewarded |\n| App install image | image_app_install | Banner, Native, Interstitial, Rewarded |\n| Display image | image_display | Banner, Interstitial |\n| Display partial slot | partial_slot | Banner, Native, Interstitial |\n| App install text | text_app_install | Banner, Native, Interstitial |\n| Display text | text_display | Banner, Native, Interstitial |\n| Trueview | trueview | Interstitial, Rewarded |\n| App install video | video_app_install | Banner, Native, Interstitial, Rewarded |\n\nThis feature impacts Google ads only. If your ad unit enables\n[mediation](/ad-manager/mobile-ads-sdk/android/mediation), ads returned from third-party ad sources don't\nrespect the `ft_ctype` parameter. We recommend testing with an ad unit that\ndoesn't have mediation enabled."]]
