eWay is now supported to have the same Pre Authorisation function as NAB Transact was earlier this year. A Pre Authorisation box will become available when the Payment Gateway Card Entry screen is loaded (either by ;PG command or on Invoice Completion) if the Invoice has yet to perform a Pre Authorisation. To determine if a Pre Card Authorisation will occur, Users will set a default in Invoice Configuration>Payment Gateway>Pre Authorisation Default.
If an Invoice is set to perform a Pre Authorisation, then the Payment Gateway will be called to perform the Pre Authorisation for the current Invoice amount, when the user presses Complete. An Invoice Conversation is automatically added detailing this.
Once an Invoice has performed a Pre Authorisation, the user is not able to do any of the following:
- Change the Terms used for the Invoice
- Change the payment details (The Card Entry screen cannot be envoked)
- Modify the Invoice to result with a Total Invoice amount greater than the Pre Authorisation amount.
On Invoice Printing, the Payment will be completed (With the current Invoice amount). In the event of a Card error, the User will be given the option to either try again, to manually process a Payment with the same Credit Card, or to Cancel.
The below will be shown when modifying an Invoice that has already performed a Pre Authorisation:
‘This Invoice has been Pre Authorised and its Total Invoice value can not exceed $99.999.’
The way ACR communicates with NAB Transact and eWay will differ slightly due to differences in each providers service.
- eWay will receive the Invoice reference number upon a completion of a Pre Authorisation whereas NAB Transact will receive the Pre Authorisation reference number.
- When the system finds a Pre Authorisation that was created without an Invoice, eWay will automatically be called upon to cancel it whereas NAB Transact will not. Note: If the cancellation fails an email will be sent to the Postmaster.
