當在PHP中使用的recurly API你怎麼在Recurly退款交易original_transaction_id
$transaction = Recurly_Transaction::get($uuid);
的$交易變量沒有一個original_transaction_id場像有在交易的導出的csv：
https://yoursubdomain.recurly.com/exports/new#transactions
人應該如何獲得通過API的original_transaction_id？

討論::更新2016年2月8日::
他們已經在PHP客戶端2.6.0版本添加了original_transaction_id ：

:: END UPDATE 8.2.2016 ::
//::HACK:: Only works when there is 1 purchase transaction.
$all_account_transactions = Recurly_TransactionList::getForAccount($refund_transaction->details[0]->account_code);
foreach ($all_account_transactions as $account_transaction)
{
if($account_transaction->action=="purchase" &&
$account_transaction->subscription->get()->uuid == $refund_transaction->subscription->get()->uuid)
{
//This is a purchase transaction and its from the same subscription as the $refund_transaction.
//If there's only 1 purchase transaction then this is your transaction that was refunded.
//If there's multiple purchase transactions you'll have to figure out which one you want to apply the refund to
