Abstract
An originating server of a payment processing system comprising multiple communicating servers first processes a transaction event, generates a correlating identifier and transmits the correlating identifier and processing information to a central data log accessible by the multiple communicating servers. One or more intermediate servers and a terminating server then process the transaction event, each successive intermediate server and the terminating server receiving the transaction event and a correlation identifier associated with the transaction event generated by the previous server which processed the transaction event. Each successive intermediate server and the terminating server generates a correlation identifier, and transmits both the received and generated correlation identifiers to the central transaction log. A query comprising a correlation identifier associated with the transaction event is received. The payment processing system extracts successive sets of entries from the central data log by matching corresponding correlation identifiers and generates a transaction event history.
