The expiry date is the date and time in which the VA expires and can no longer be paid into. Payments made after expiry date will be rejected. The default expiry date for invoice VAs is 24 hours. To change the default expiry date, please contact our customer support. Fixed VAs have no default expiry date, but users can set one in the create VA API request (see our api reference docs for more information). Note: Times are in UTC format.
