Out of Band Transaction Notifications

Out of Band Transaction notification is a dedicated messaging system that allows merchants to receive their transaction outcome reliable and timeously. The transaction outcome available in the Out of Band notification system contains the same data elements as would be found when doing a transaction look up in the gateway's endpoint or directly from Backoffice. Merchant developers can implement a webservice that will consume the transaction notification payload. The transaction notifications are usually available when the cardholder completes a payment to the merchant.

Format of the OOB Transaction Notification

• The transaction notifications to the merchant are JSON formatted, the body of the message contains a Base64 string of the VXML response. The VXML response parameters are defined in the Output Parameters per action.
