(Delphi DLL) CardConnect Settlement Status

Demonstrates how to get the status of transactions which have been submitted to the processor for settlement.

The settlement status service returns the status of transactions which have been submitted to the processor for settlement. The transaction’s setlstatus is updated appropriately when CardConnect’s receives a response from the processor. You can either specify a batchid to return a specific batch of transactions, or use a date to return all transactions settled for that date. ...
