The IndiGo Server as well as the iVeri Gateway operates in Host Settlement rather then Terminal Settlement mode. This means that a transaction is settled in the cycle that the Host is in when a transaction arrives at the Host. The cycle into which a transaction’s settlement will fall is allocated at the time of the transaction and returned in the AcquirerReference number, which is a composite field consisting of the Settlement Cycle Number and the Transaction Trace assigned by the Acquirer.
For the Integrator to be able to generate statements which match the bank statement the Integrator needs to produce reports based on the Settlement Cycle number received from IndiGo at the time of the transaction. By doing this the value of the settlement deposited into the Merchant's account can be shown to be the sum of successful financial transactions which have the same Settlement Cycle.
