Mailchimp API - пакетная загрузка

Question

Я пытаюсь импортировать список из 879 пользователей (в пакетном режиме) в список Mailchimp.Библиотека, которую я использую: https://github.com/pacely/mailchimp-api-v3.

Я создал консольную команду Laravel для этого.Код:

<?php

namespace App\Console\Commands;

use Illuminate\Console\Command;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Validator;
use Mailchimp\Mailchimp;
use Exception;

class ImportContactsIntoMailchimp extends Command
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'mailchimp:import:contacts';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'Import contacts into mailchimp.';

    /**
     * Create a new command instance.
     *
     * @return void
     */
    public function __construct()
    {
        parent::__construct();
    }

    /**
     * If an e-mail address starts with this, mailchimp won't allow it
     * http://kb.mailchimp.com/lists/growth/limits-on-role-based-addresses
     *
     * @var array
     */
    private $nomail = array(            
        'abuse@',
        'admin@',
        'billing@',
        'compliance@',

        'www@'
    );

    /**
     * Execute the console command.

     * @return mixed
     */
    public function handle()
    {
        $result = DB::table('contacts_billonline')
            ->select(
                'email',

                    break;

                // Is this a valid email address? If so add it to the batch
                if ($this->isValidEmail($email)) {

                    $this->info($email);

                    // Get our merge columns for this row and put them in the array
                    $merge_fields = array();
                    foreach ($merge_columns as $key => &$column) {
                        $merge_fields[$key] = &$result[$row_number]->{$column};
                    }

                    $insert_email = array(
                        'email_address' => $email,
                        'status'        => 'subscribed',
                        'merge_fields'  => $merge_fields,

            $this->info($batch_result);

    /**

    function IsValidEmail(&$email)
    {
        foreach ($this->nomail as &$bad_mail)
        {
            if (strpos($email, $bad_mail) === 0)
            {
                return false;
            }
        }

        $validator = Validator::make(
            array(
                'email' => &$email
            ),

        if ($validator->fails())
        {
            return false;
        }

        return true;
    }

}

Я пытаюсь импортировать пользователей из таблицы базы данных в пакетном режиме в Mailchimp.

Ключ API установлен правильно.Я также пытаюсь установить тег «Контакты» для подписчиков.

Идентификатор списка также установлен правильно.

Проблема в том, что список не импортирован.Результат в терминале:

{"id": "c48cd17f6d", "status": "pending", "total_operations": 0, "done_operations": 0, "errored_operations": 0,"submitted_at": "2019-07-02T10: 58: 22 + 00: 00", "completed_at": "", "response_body_url": "", "_ ссылки": [{ "отн": "родитель", "HREF":" https://us8.api.mailchimp.com/3.0/batches","method":"GET","targetSchema":"https://us8.api.mailchimp.com/schema/3.0/Definitions/Batches/CollectionResponse.json","schema":"https://us8.api.mailchimp.com/schema/3.0/CollectionLinks/Batches.json"},{"rel":"self","href":"https://us8.api.mailchimp.com/3.0/batches/c48cd17f6d","method":"GET","targetSchema":"https://us8.api.mailchimp.com/schema/3.0/Definitions/Batches/Response.json"},{"rel":"delete","href":"https://us8.api.mailchimp.com/3.0/batches/c48cd17f6d","method":"DELETE"}]}

Что я делаю не так?
