Abstract: To execute an ecommerce purchase transaction between a customer and merchant using rewards points made available to the customer through a rewards program provider, a system executes a transaction with the merchant and the rewards program provider. The system receives a customer request to execute the purchase using rewards points. Additionally, the system retrieves customer reward points information responsive to a customer authorization and determines a redemption rate for redeeming the rewards points to transaction currency. The system executes a redemption transaction with the rewards program provider, thereby receiving transaction currency in exchange for released points. The system also executes a transaction with the merchant, purchasing one or more customer selected item on behalf of the customer using transaction currency. Finally, the system provides the user with updated reward points account information.
