A debit cardholder purchases $250 worth of goods at a gift shop in Barcelona, Spain. A little while later the cardholder returns one $50 item to the shop. The shop refunds $50 to the cardholder on the card that was used to make the purchase. The following are true:
The initial available balance is $1000.
The merchant validates the debit card with a signature.
The network is Mastercard Banknet.
The cardholder returned the item before the transaction cleared.
The authorization and settlement amounts are in dollars, converted from the foreign currency.
Sequence of events
Events in the same step have the same timestamp.
Mastercard sends an authorization request for –250.00.
Galileo approves the request and places a 250.00 hold on the cardholder account. The available balance is now 750.00. Galileo sends a BAUT: auth webhook.
The merchant sends an authorization reversal for 50.00.
Galileo removes 50.00 from the hold. The available balance is now 800.00. Galileo sends an AAAU: auth webhook.
Mastercard sends a batch file with –202.00 as the settlement amount, after applying currency conversion to the remaining 200.00.
Galileo backs out the 250.00 hold and posts –202.00 to the account. The available balance is now 798.00. Galileo sends a SETL: setl webhook.
