У меня были проблемы с обработкой сообщений PayPal IPN в разрабатываемом веб-приложении. Я обратился в службу технической поддержки PayPal Merchant за информацией об обработкеReversed, Canceled_Reversed а такжеRefunded Сообщения IPN. Этот код ниже, что я нашел полезным из их ответов. Я надеюсь, что это будет использовать и другие:

Оплата:

Когда спор подается в центр разрешения PayPal: этот IPN имеет тот же txn_id первоначального платежа

{
    "txn_type":"new_case",
    "payment_date":"15:51:55 May 02, 2014 PDT",

Сумма на удержании (payment_status являетсяReversed): Txn_id первоначального платежа - parent_txn_id. У него новый txn_id.

}
