Is there a field for knowing if the youtube channel is verified from the Youtube API?

Question

I am using the Youtube data API and I needed to know if there is any way of finding that the youtube channel is a Verified one.

Answer 1

just ran into this today, and while the channelBranding of the V3 youtube API looks promising, I couldn't get it to return if the account/channel user id was verified or not

so I threw up a pretty lame php script that uses DOM model searching to examine the html directly. to return true if the following element is present.

<a href="//support.google.com/youtube/bin/answer.py?answer=3046484&amp;hl=en" class="qualified-channel-title-badge" target="_blank">

As of today (9/8/2014) a verified user will return true..

<?php
function isVerified($youtubeUser) 
{ 
    $youtubeUser = trim($youtubeUser); 
    $url = '\''."https://www.youtube.com/user/".$youtubeUser.'\'';
    $url = "https://www.youtube.com/user/".$youtubeUser ;
    $Verified = false;
    echo "<BR>looking at $url "; 

    $ch = curl_init();
    $timeout = 10;
    curl_setopt($ch, CURLOPT_URL, "$url");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
    $html = curl_exec($ch);
    curl_close($ch);

    $dom = new DOMDocument;
    @$dom->loadHTML($html);

    foreach ( $dom->getElementsByTagName('a') as $link ) {
        $myVar = $link->getAttribute('class');
        $search = "qualified-channel-title-badge";
        $found=false;
        $found = strpos($myVar, $search); 
        if ( $found  !== false) { 
            $Verified = true;  //echo "<BR><font color=green>TRUE</font>";
        } else {
            $Verified = false; //echo "<BR><font color=red>FALSE</font>";
        }
    } 

    if ( $Verified ) {
    return true;
    } else {
    return false;
    }
}
?>

Bye for now!

RE: mpgn's solution, note that there's a distinction between whether the G+ account is Verified and whether one or more of the accounts YouTube channels are Verified. It's possible for an account to have more than one channel, and each of those channels are verified independently, and for channels to be unverified even though the associated G+ account is verified.

As @Paul Blakely suggests, the current best way to do this is to check the status.longUploadStatus flag, per https://developers.google.com/youtube/v3/docs/channels
