The Budget Period facility is only available within certain localities (e.g. South Africa), and therefore only currently available with distributor Nedbank.
Since a transaction sequence may entail the Budget Period being sent to the acquirer multiple times, the merchants should ensure that this value is consistent.
If an authorisation was obtained outside the iVeri Gateway, and then the AuthorisationCode is sent within “Debit with PAN” or “Debit with Track2”, then the BudgetPeriod should be set to the same value as when authorised.
If the BudgetPeriod is not sent to the iVeri Gateway, then iVeri assumes to be “straight” (0 months). However, if the external authorisation was “over budget”, then it would then be up to the acquirer/issuer to decide between the conflicting budget values.
