 * See PurchaseRequest for the first part of this example transaction:
 *
 * <code>
 *   // Fetch the balance to get information about the payment.
 *   $balance = $gateway->fetchBalanceTransaction();
 *   $balance->setBalanceTransactionReference($balance_transaction_id);
 *   $response = $balance->send();
 *   $data = $response->getData();
 *   echo "Gateway fetchBalance response data == " . print_r($data, true) . "\n";
 * </code>
