Create New Authorizations

You can process additional authorizations for your customers without having to store or require the customer to enter billing and shipping address and payment card information on your web site. Instead, you retrieve a previous authorization in the Business Center and use the information from that order to process a new one. New Authorizations (reauthorizations) enable you to process a new transaction linked to the original. The payment information must be the same as the original transaction. The information is then added to the Related Transaction section of your original transaction. Expired authorizations require a new authorization and cannot be settled. If the transaction is not initiated by the cardholder, you must identify the transaction as merchant-initiated and provide one of the following reasons for the new transaction:
  • Resubmission
  • Delayed charge
  • Reauthorization for split shipment
  • No show
  • Incremental authorization
