Scenario 4: Reversal on Authorization Before Clearing (Mastercard)
A debit cardholder makes an online purchase for $10 using a mobile wallet. A couple hours later, the cardholder cancels the transaction. The transaction does not clear before the reversal. The following are true:
- The initial available balance is $1000.
- The network is Mastercard Banknet.
- Transactions for this merchant type and amount are configured to expire after seven days.
Sequence of events
Events in the same step have the same timestamp.
- Mastercard sends an authorization request for –10.00.
- Galileo approves the request and places a 10.00 hold on the account. The available balance is now 990.00. Galileo sends the
BAUT: authevent message. - Mastercard sends a reversal for 10.00.
- Galileo reverses out the 10.00 hold. The available balance is now 1000.00. Galileo sends an
AAAU: authwebhook. - After seven days, the authorization and its reversal expire. Galileo sends the
BEXP: auth_expandBEXR: auth_exp_reversalevent messages.
