In the CRM:

• Finance –> Transactions and search the transaction..

On the server (deep debug, logs)

• for EVERY Gateway (SafeCharge, Skrill, etc.) , EVERY DAY - there is a new log file (if it does not exist, then there were no attempted transactions via that gateway that day)
• on web-server:
• c:\inetpub\wwwroot\Gnuhost.Trader.Web\Logs
• inside there, will be a folder with domain-name (in this case, domain.com)
• inside there are all logs for that domain
• !OLD is a folder containing older log files - moved manually
• find the log for gateway/date
• all info is inside there
• we have 2/3 logs there:
• 1. Initial Client Request
• this is a list of all POST params sent to the gateway to initiate the transaction
• 2. Failure Page (or something similar - depends per gateway)
• this will show you params returned by callback from the gateway
• this, of course, is super-useful in the event that something goes wrong
• we can take that and use it to debug the problem
