Abstract: Computer-implemented offer redemption process including receiving notification from supported trackers, each having a different known configuration, to enable each supported tracker to pass field/s, specific to the configuration, in which an ID of a content offer is stored. The offer is defined as a quantity of a currency, to an advertiser having an account, upon app installation. Responsively to receipt of notification, offer id and/or advertiser account is validated using field/s in which offer's ID is stored. If validated, processor is used for redeeming the offer including generating and storing a voucher with unique voucher ID on computer storage medium, passing voucher ID, user/device id, app identifier, and currency and quantity to advertiser such that advertiser can enable the quantity of the currency in an app identified by the app identifier, for the user/device. Generated voucher is marked “redeemed” to prevent recurring redemption.
