Notification callback
Computop server will execute an HTTPS POST request directly to the web server of the Partner (URL) . To integrate with this notification, the Partner should supply Computop with the IP address and the URL that leads to the callback entry point of the server. This is usually a small module/application, which constantly listens and waits for incoming HTTPS requests from the Computop server. The Computop server will send data via an HTTPS POST request to the server URL configured including all the relevant parameters in the HTTPS POST request.
The parameters will be transmitted in the HTTP Body as a Blowfish encrypted parameter string. The content type will be application/x-www-form-urlencoded; charset=iso-8859-1.
Note: Please note that the Notify-call is permitted only via Port 443 (SSL) for security reasons. The URL encoded parameters are transmitted in key-value pairs.
If one of these parameters (IP or URL) during time changes, the partner should notify Computop Helpdesk to perform the related configuration changes.
For security reasons a common BlowfishSecret Key (password) will be shared between Computop and the Partner regarding this notification process and the parameter MAC should be present in the callback request.
The calculation of the MAC value is done using SHA-256 algorithm and with the subsequent parameter values: PayID*XID*TransID*MerchantID*Status*Code.
The receiver should use the MAC SHA-256 algorithm, which nearly all programming languages support, to calculate the hash value with the HMAC key and the parameter values.
Computop Paygate will submit a notification request via HTTP POST in order to transfer the authorization status and transaction details to the server URL as stored in the merchant configuration.
The following table describes the result parameters with which the Computop Paygate responds to your system
pls. be prepared to receive additional parameters at any time and do not check the order of parameters
the key (e.g. MerchantId, RefNr) should not be checked case-sentive
