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"]]
