Paymentech, Additional Credit Card Parameters (Legacy)
In addition to the parameters in Table 4.1 , “Credit card transaction request parameters,”
Paymentech accepts the following legacy parameters. For best AVS results, pass the city and
state parameters in the parameter list.
RECURRING Identifies the transaction as recurring. This value
does not activate the PayPal Recurring Billing
Service API.
If the RECURRING parameter was set to Y for the
original transaction, then the setting is ignored when
forming Credit, Void, and Force transactions.
If you subscribe to PayPal’s Fraud Protection
Services:
To avoid charging you to filter recurring
transactions that you know are reliable, the fraud
filters do not screen recurring transactions.
To screen a prospective recurring customer, submit
the transaction data using PayPal Manager’s Virtual
Terminal. The filters screen the transaction in the
normal manner. If the transaction triggers a filter,
then you can follow the normal process to review
the filter results.
