METHOD AND SYSTEM FOR PROCESSING OF A REAL-TIME REBATE AT TRANSACTION AUTHORIZATION

A method for initiating a rebate for a payment transaction funded using a reward account includes: storing account data entries, each entry including an account identifier and reward balance; receiving an authorization request for a transaction involving a merchant, the request including payment information and a transaction amount; calculating a transaction reward value based on the transaction amount and a conversion rule; identifying a reduction amount, wherein the amount is a lesser of the transaction reward value and the reward balance included in a data entry where the account identifier corresponds to the payment information; updating the reward balance included in the data entry based on the identified reduction amount; calculating a rebate amount based on the transaction reward value and reduction amount, and the conversion rule; and transmitting a rebate request for the rebate amount from an account of the merchant to an account corresponding to the payment information.
