The transaction postback gets posted when a transaction (payment, refund etc.) has been successfully processed.
It contains all the details related to the payment.



It's recommended that you save the Vendo Transaction ID and the Vendo Subscription ID for future reference and processes like One-clicks, Instant Upgrades, Cancellations, Refunds and so on.
