Formato VPOSNotification
========================
Pag 49, messaggio http inviato con metodo POST, in modalità SSL.
Rappresenta il messaggio inoltrato da X-PAY agli URL (NOTIFICATION_URL e RESULT_URL)
specificati dall’esercente nel messaggio di apertura dell’ordine (VPOSReqFull o nel
nostro caso VPOSReqLight), per potergli comunicare l’esito positivo della transazione.
La comunicazione verso il NOTIFICATION_URL avviene tramite una chiamata diretta server
to server, quella verso il RESULT_URL avviene tramite il browser dell’acquirente.
Parametri:
* TERMINAL_ID
* TRANSACTION_ID
* RESPONSE -> TRANSACTION_OK
* AUTH_CODE -> alfanum max 10 char (codice auth ricevuto dall'emittente della carta di credito, anche con spazi)
* TRANSACTION_DATE -> gg/mm/aaaa hh.mm.ss
* CARD_TYPE -> tipo carta usata (es VISA)
* AMOUNT
* CURRENCY
* TRANSACTION_TYPE, tipo transazione con livelli di sicurezza (vedi App A2)
* MAC
Es: TERMINAL_ID=0000000050242004&TRANSACTION_ID=T000000000000000001&RE
SPONSE=TRANSACTION_OK&AUTH_CODE=901867&TRANSACTION_DATE=06/07/2005
16.55.56&CARD_TYPE=VISA&AMOUNT=000123056&CURRENCY=978
&TRANSACTION_TYPE=VBV_FULL&MAC=70C4F1F621A5DED95C7EE8C5507A9E1F297
0BCFE®ION=Europe&COUNTRY=Italy&PRODUCT_TYPE=Consumer&LIABILITY_
SHIFT=N
I parametri utilizzati per il calcolo
questo tipo di messaggio sono i seguenti:
o TERMINAL_ID
o TRANSACTION_ID
o RESPONSE
o AMOUNT
o CURRENCY
o Chiave per MAC
Al termine ritorna una VPOSNotificationRes
