[thelist] authnet - how do you store the required fields untilthey are sent?

I was going to store the authorize.net transaction id, but not any of the
credit card info. Can I reverse/adjust a transaction with only the id or do
I need to keep the last four digits and exp date as well?
Thanks for your help!

That's what I do, but in a Java environment where session data isn't written
to disk.

Can you configure your PHP instance to use the database to persist session

Also, consider keeping the entire transaction as a record in the DB; that
way you can also save Authorize.net's transaction id plus the last four
digits and expiration date of the CC, which you'll need if you have to
reverse or adjust a transaction.
