The following rules apply to all Incremental Authorizations:

• Incremental authorizations are not standalone transactions. They must reference an original CreditAuth
• Approved Incremental authorizations increase the total settlement amount of the original CreditAuth
• The transaction ID of the original CreditAuth is used for all subsequent actions (i.e., voids, reversals, edits, etc); the transaction ID of the incremental authorization should never be referred to by subsequent transactions.
• If the final settlement amount of the original transaction is less than the cumulative authorized amount (original authorization + incremental authorizations), a partial reversal will automatically be generated for the difference
• The original transaction must be a fully approved CreditAuth

 

NOTE:  Merchants processing via Portico to the Exchange authorization platform may perform incremental authorizations where the original transaction is either a CreditSale or a CreditAuth; however, CreditAuth should be used for all new integrations.
