For example, if your master account is 99999 and the subaccount is 100, your Decline Page would be named b99999100.hmf. Runtime Variables used to pass information from start to finish in a transaction. These runtime variables are valid in all credit card transactions. They're called pass-through variables, and they allow you to insert live data from your own system into the Approval Page being transmitted from our system. When iBill receives a form with ref1, ref2, etc., data in it, iBill holds that data in memory pending the success of the credit card charge.
Some clients use pass-through variables to track where the customer came from.
Some clients use them to enter the account number of an originating site. Many never see a need to use them at all. It's entirely up to you. Copyright Policy Information subject to change without notice. Inc. All rights reserved.
