Payflow and credit card details storage

[Dev_guy]

When we used PayPal REST API - we could use PayPal Vault in order to save credit card details and use vault card's id in PayPal transactions.

If we migrate on Payflow - what approach should be taken (to meet PCI compliance)?

[Payflow_Todd]

On Payflow we do what is called reference transactions whereas you send us the data originally, we reply with a PNREF (transaction id) and any additional transactions can be done with this ID.

So, the idea is do a $0 authorization to verify card details, then a reference  transaction for the actual transaction and any future ones. 

See https://developer.paypal.com/docs/payflow/integration-guide/submit-transactions/#submit-reference-tr...

I checked the Reference Transaction documentation but the Payflow Pro transaction IDs (PNREFs) are valid for use in Reference Transactions for 12 months and possibly up to 15 months.

I don't want a life time limit to search the credit card details

Any solution?
