CreditTxnEdit allows the merchant to alter the data on a previously approved CreditSale, CreditAuth, CreditOfflineSale, or CreditOfflineAuth (i.e. add a tip amount).
Note:Depending on the Host Processor, a CreditOfflineAuth transaction may not be modified after it has been added to a batch.
Note:The gateway will not submit an authorization or reversal when the settlement amount of a transaction is altered. The client is responsible for managing these adjustments as needed.
Note:Approved UnionPay authorizations routed directly to UnionPay International cannot be adjusted. UnionPay cards routing through either the Discover or JCB networks may be adjusted. (UnionPay direct routing available for Canada merchants on the GSAP authorization platform only).
