is this "createOrUpdate()" API available only for Pro version?

I want to use company create method to create company in fluentCRM via custom code once company created in fluent forms, this is my current code:

add_action('acf/save_post', 'sync_company_with_fluentcrm', 20);

function sync_company_with_fluentcrm($post_id) {
    if (get_post_type($post_id) !== 'company') return;

    // read ACF data
    $data = [
        'name'     => get_field('company-name', $post_id),
        'email'    => get_field('company-email', $post_id),
        'phone'    => get_field('company-phone', $post_id),
        'website'  => get_field('company-url', $post_id),
        'vat_number' => get_field('company-vat', $post_id),
        'owner_id' => get_post_field('post_author', $post_id),
    ];

    // API used
    $companyApi = FluentCrmApi('companies');
    $company = $companyApi->createOrUpdate($data);

    if ($company && $data['owner_id']) {
        // connect owner with contact
        $companyApi->attachContactsByIds([$data['owner_id']], [$company->id]);
    }
}
