Obtenga detalles (pago principal) de un reembolso

¿Cómo es posible obtener el pago principal de un reembolso, que PayPal me notificó?

Recibí esta notificación (webhook) de 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" } 

Si tomo el recurso -> id y realizo la siguiente solicitud con PayPal PHP-SDK, obtengo un objeto de reembolso pero sin el campo “parent_payment” (documentado aquí: https://developer.paypal.com/docs/api/ # look-up-a-refund )

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

Cada otra llamada como …

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

o

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

o

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

¡falla!

¿Qué pasa con mis notificaciones o los métodos que estoy usando?

ACTUALIZACIÓN : Aquí está mi respuesta de la búsqueda de Refund :: get ():

 { "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" } ] } 

En general, cuando realiza una búsqueda en Refund , obtendrá una respuesta que incluye parent_payment que debe tener el PaymentID que podría utilizarse para recuperar el objeto de pago.

Así es como se vería la respuesta:
