Using the Data API youtube v2 (Error No longer available)

Good afternoon,

I'm trying to solve a problem on a page, where youtube API is used, to bring the videos of a certain channel. however, he recently started giving the No longer available error. I'm not sure what version of the API is being used, but it's probably V2, maybe a solution would be the migration to V3, but I do not know how to do it, I've read some documents, but I was not successful.

Someone has already gone through this and can you help me?

Alias, I'm using the script:

<script type="text/javascript">
    ytEmbed.init({
        'block':'youtubeDiv',
        'paging':false,
        'type':'user',
        'q':'Zenimotors',
        'results':'48',
        'display_first': true, 
        'order':'new_first'
    });
</script>

Thank you!
