Setting purchase order number or customer reference number with PayPal Payflow

Question

Using PayPal Payflow with hosted pages (and submitting using NV pairs), when reviewing transactions using the "Search Transactions" functionality in PayPal Manager, there is an ability to search by Purchase Order Number. Additionally, when viewing details for a transaction, there is a Cust Ref #.

I have not been able to figure out how to set either of these values - the customer reference # is always blank, and the search by purchase order never returns results.

Is there any way to set these fields during the process?

Answer 1

CUSTREF for customer reference
PONUM for purchase order

Note: These fields might not be supported by every Processing Platform

Answer 2

I did not find a solution for this, but I did find that COMMENT1 and COMMENT2 can be added as names in name-value pairs - this will cause the corresponding fields in the PayPal Manager transaction search to be populated.
