The Open Refund transaction type (non-tagged) is used for transactions that may not have necessarily been processed through the Payeezy Gateway. Tagged Refunds are limited to the amount of the original completion. Non-Tagged Refunds can be utilized to issue transaction credits not associated to an Payeezy Gateway completion transaction.
Using an Open Void transaction type (non-tagged) through the RPM (Real-time Payment Manager), someone can submit a void transaction utilizing an authorization number that may have been obtained elsewhere. The Tagged Void transaction is used for existing transactions in the system to run voids before the transaction is settled.
