Corporate card integration using masked credit card file and combi-pay file with actual card numbers

Summary:

During credit card integration client would receive the masked card numbers. Citi Bank wants to receive a combi-pay file to conduct their reconciliating based on the actual credit card numbers. Citi bank is expecting client to provide the actual card numbers along with payment amount for each card in the combi-file. As Oracle will not ingest the actual card numbers hence is not stored in backend. We would like to know if Oracle has implemented or build any solution for outbound combi-pay file with actual card numbers?

Appreciate any experience/solution shared regarding this.
