php - YouTube API v3 not retrieving videos for a channel -

ok, i've used following php code try youtube return users list of videos, however, "items" coming empty.

$apikey         =   "my-api-key"; $channel_name   =   "ucszdpmgfgxdgm4ytnm4arta"; $count          =   1;  $apiv3          =   json_decode(file_get_contents("https://www.googleapis.com/youtube/v3/channels?part=contentdetails&forusername=".$channel_name."&key=".$apikey)); foreach($apiv3->items $item):     $uploads = $item->contentdetails->relatedplaylists->uploads; endforeach;  $youtube        =   json_decode(file_get_contents("https://www.googleapis.com/youtube/v3/playlistitems?part=snippet&contentdetails&maxresults=".$count."&playlistid=".$uploads."&key=".$apikey));         return $youtube; 

and being returned:

{  "kind": "youtube#channellistresponse",  "etag": "\"tbwc5xrsxxe1woax6mk9z4hhsu8/3cxjrxf86g9z5bg7rup3qfcgrxm\"",  "pageinfo": {   "totalresults": 0,   "resultsperpage": 5  },  "items": [  ] } 

yet on page, have uploaded videos. how work? i've used exact same code on user , works fine.

you can use video search api instead. use list method channelid parameter. grab url:

https://www.googleapis.com/youtube/v3/search? part=snippet&channelid={the_channel_id}&key={your_api_key} 

the response (copied try it section):
