DPM allowable merchant-defined field values

I'm using sessions with DPM in test mode.  I want to know whether a card was accepted or rejected for a given session.

DPM's relay response usually starts a new session.  To correlate the response to the original session, I put a hash of my

session ID in a merchant-defined field called "my_session_id".  One example of a hashed session id is:

"cfaebe70125a6e64990f15b9b7739d22a1e9f2f1".  Unfortunately, AN converts that hash to an asterisk when

the transaction fails.  It doesn't alter it when the transaction succeeds.  Obviously, I can't correlate to the original session

if AN changes it.

 

Reading other posts, AN will convert certain merchant-field contents to an asterisk if it looks like unallowable data (credit

card number, etc.)  I wonder if a hash falls into that category.  I considered changing the merchant-defined field value to a
date appended with a 5- or 6-digit number, but before I spend the time coding it up, I want to make sure it will work.  I'd

like to know:

 

1. What is a sure-fire format for a session ID that AN will always allow and never convert to an asterisk?

 

Thanks,
Charles
