Scenario 1:

When attempting to send sync and fullsync messages between systems, the application server times out while waiting for an http response and above error occurs.



Scenario 2:
When attempting to integrate Campus Solutions with a 3rd party payment provider, specifically via synchronous messages, the following error on the Review Transaction Log page (Student Financials > Charges and Payments > Electronic Transactions > Electronic Payments > Review Transaction Log):

An error occurred processing the Service Operation (Error:  Integration Gateway - External System Contact Error (158,10721)). (14869,717)

The epayment transaction shows as declined on Campus Solutions.  Further investigation at the payment provider site shows the payment was authorized and was successful.  The credit card, or bank account will be charged for the purchase but the successful payment is not reflected on Campus Solutions.  This is known as a 'false decline'.
