config/app.php

Add youtube credentials into config

'youtube' => [
	'api_key' => env('YOUTUBE_API_KEY', ''),
	'channel_id' => env('YOUTUBE_CHANNEL_ID', ''),
],

YoutubeCountConsole

Create console class for getting number of subscribers

<?php

namespace App\Console\Commands\Youtube;

use App\Models\SocialCount;
use Illuminate\Console\Command;
use Illuminate\Support\Facades\Http;
use Illuminate\Cache\Repository as Cache;

class YoutubeCountConsole extends Command
{
    /**
     * @var string
     */
    protected $signature = 'youtube:count';

    /**
     * @var string
     */
    protected $description = '';

    /**
     * @return void
     */
    public function handle(Cache $cache)
    {
        // Credential
        $youtubeChannelId = config('services.youtube.channel_id');
        $youtubeApiKey = config('services.youtube.api_key');

        // HTTP CLient
        $response = Http::get('https://www.googleapis.com/youtube/v3/channels', [
            'part' => 'statistics',
            'fields' => 'items/statistics/subscriberCount',
            'id' => $youtubeChannelId,
            'key' => $youtubeApiKey,
        ]);

        //
        if ($response->successful()) {
            // Response
            $json = $response->json();

            /* Data */
            $count = $json['items'][0]['statistics']['subscriberCount'];

            echo $count . "\n";
        } else {
            echo $response->body() . "\n";
        }
    }
}
