Reverse a Payment

Authorization Reversal Service Sequence Diagram

Process

To reverse a payment, an Authorization must have been completed. When the Payment Update API Extension receives a payment that contains an INITIAL CANCEL_AUTHORIZATION transaction, it will attempt to reverse the requested amount on the transaction using the interactionId of the existing SUCCESS AUTHORIZATION transaction on the payment. The requested amount must be equal to the amount original authorized.

Steps

To reverse a payment:

• Complete an authorization, ensuring that the state is Success
• Update the payment, adding an INITIAL CANCEL_AUTHORIZATION transaction onto the payment with an amount matching the amount of authorization being reversed

Cancel Authorization Response Handling

• A successful reversal will change the INITIAL CANCEL_AUTHORIZATION to a SUCCESS CANCEL_AUTHORIZATION transaction, adding the Reversal Request Id onto the transaction as an interactionId

• If the reversal is not successful due to any reason, the extension will change the INITIAL CANCEL_AUTHORIZATION to FAILURE CANCEL_AUTHORIZATION transaction along with adding the Reverse Request Id onto the transaction as an interactionId. One can request a cancel authorization again if it is failed
