Five-Step Sequence Simulation
A cardholder makes a $25 transaction at a gas pump. This is the same transaction shown in Five-step sequence in Card Transaction Examples, except that these examples show Mastercard instead of Visa. Also see Scenario 2: Preauthorization with Completion.
In Production, most gas pump transactions arrive at Galileo over interbank (PIN) rails. However, the simulator only simulates Visa credit or Mastercard credit rails.
Preauthorization
Call Create Simulated Card Authorization with these parameters:
| Parameter | Value |
|---|---|
accountNo | PAN or PRN |
amount | 1 if you have upcharges configured for MCC 5542 or 75 if you do not |
association | visa or mc_auth |
merchantName | Central Gasoline |
mcc | 5542 |
transType | 2 |

}
Capture the auth_id for later use.

Completion
Call Create Simulated Card Authorization with these parameters to simulate the completion, because a completion comes to Galileo through the authorization stream.
| Parameter | Value |
|---|---|
accountNo | PAN or PRN |
amount | 25 |
association | visa or mc_auth |
mcc | 5542 |
originalAuthId | auth_id from previous response |

}
Capture the auth_id for later use.
View the Completion
Call Get Authorization History to see the completion. Notice that the preauthorization is no longer present. It has been replaced by this completion, which has a new auth_id, and 25 is the new hold amount. When you settle the transaction, you settle this completion. The original_auth_id field contains the auth_id from the preauthorization.
