Systems and methods for automated transactional offers are disclosed. The system may receive an extension communication comprising a merchant uniform resource locator (URL) and an offer ID. The system may filter verified merchant URLs based on the merchant URL. The system may retrieve an available offer based on a merchant ID associated with the verified merchant URL. The system may transmit the available offer to a user device. In response to the user device accepting the offer, the system may enroll the user for the offer at an issuer system, to enable the offer to be applied during processing of the associated transaction.
