獲得退款的詳細信息（父支付）

Question

如何獲得由PayPal通知我的退款的父付款？

我得到這個通知（網絡掛接）來自PayPal：

{ 
    "create_time": "2015-02-20T10:56:36Z", 
    "event_type": "PAYMENT.SALE.REFUNDED", 
    "id": "WH-XXX-XXX", 
    "links": [ 
    { 
     "href": "https://api.paypal.com/v1/notifications/webhooks-events/WH-XXX-XXX", 
     "method": "GET", 
     "rel": "self" 
    }, 
    { 
     "href": "https://api.paypal.com/v1/notifications/webhooks-events/WH-XXX-XXX/resend", 
     "method": "POST", 
     "rel": "resend" 
    } 
    ], 
    "resource": { 
    "amount": { 
     "currency": "EUR", 
     "details": { 
     "subtotal": "-XX.XX", 
     "tax": "XX.XX" 
     }, 
     "total": "-XX.XX" 
    }, 
    "create_time": "2015-02-20T10:55:10Z", 
    "id": "XXX", 
    "links": [ 
     { 
     "href": "https://10.73.133.169:17881/v1/payments/refund/XXX", 
     "method": "GET", 
     "rel": "self" 
     } 
    ], 
    "state": "completed" 
    }, 
    "resource_type": "sale", 
    "summary": "A EUR XX.XX EUR sale payment was refunded" 
} 

如果我走資源 - > ID和做與PayPal的PHP-SDK下面的請求，我獲得退款的對象，但沒有「 parent_payment」字段（在這裏記載：https://developer.paypal.com/docs/api/#look-up-a-refund）

PayPal\Api\Refund::get($id, $api); 

每隔呼叫如..

PayPal\Api\Sale::get($id, $api); 

或

PayPal\Api\Transaction::get($id, $api); 

或

PayPal\Api\Payment::get($id, $api); 

失敗！

我的通知或我正在使用的方法有什麼問題？

UPDATE：這是從我的退款響應::得到（）查找：

{ 
    "id": "XXX", 
    "create_time": "2015-02-20T10:55:10Z", 
    "state": "completed", 
    "amount": { 
    "total": "-XX.XX", 
    "currency": "EUR", 
    "details": { 
     "subtotal": "-XX.XX", 
     "tax": "XX.XX" 
    } 
    }, 
    "links": [ 
    { 
     "href": "https://api.paypal.com/v1/payments/refund/XXX", 
     "rel": "self", 
     "method": "GET" 
    } 
    ] 
}

一般來說，當你做一個lookup on Refund，你會得到迴應，包括parent_payment應該有可用於檢索付款對象的PaymentID。

這是響應會是什麼樣子：

退票：get（）方法

{ 
"id": "3KJ86032KA", 
"create_time": "2015-02-23T22:25:31Z", 
"update_time": "2015-02-23T22:25:31Z", 
"state": "completed", 
"amount": { 
    "total": "-0.01", 
    "currency": "USD" 
}, 
"sale_id": "4JE73984NP0170710", 
"parent_payment": "PAY-0J694581CG996145EKTV2RWA", 
"links": [ 
    { 
     "href": "https://api.sandbox.paypal.com/v1/payments/refund/3KJ86032KA", 
     "rel": "self", 
     "method": "GET" 
    }, 
    { 
     "href": "https://api.sandbox.paypal.com/v1/payments/payment/PAY-0J694581CG996145EKTV2RWA", 
     "rel": "parent_payment", 
     "method": "GET" 
    }, 
    { 
     "href": "https://api.sandbox.paypal.com/v1/payments/sale/4JE73984NP0170710", 
     "rel": "sale", 
     "method": "GET" 
    } 
] 

}
