RECURRING Identifies the transaction as recurring. This value does not
activate PayPal’s 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 Managers Manual
Transactions page. 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.
