Get

API calls which return a single resource return a DataTransferObject with the returned data accessible via properties.

$client = $freshBooksClient->clients()->get($accountId, $clientId);

echo $client->organization; // 'FreshBooks'
$client->only('organization')->toArray(); // ['organization' => 'FreshBooks'];

visState numbers correspond with various states. See FreshBooks API - Active and Deleted Objects for details.

use amcintosh\FreshBooks\Model\VisState;

echo $client->visState; // '0'
echo $client->visState == VisState::ACTIVE ? 'Is Active' : 'Not Active'; // 'Is Active'

echo $clients->clients[0]->organization; // 'FreshBooks'

foreach ($clients->clients as $client) {
    echo $client->organization;
