Abstract: A method and system for fulfilling in-application product redemption requests is described. A fulfillment system receives a product search application programming interface (API) call from an application. The product search API includes a set of at least one product criterion received from an application. An aggregated catalog is searched based on the set of at least one product criterion. A set of product metadata is returned. The set of product metadata corresponds to at least one product that matches the set of at least one product criterion. A redemption API call that includes product information and a physical address is also received from the application. A fulfillment request is sent to an online retail platform separate from the fulfillment system via a fulfillment API call that includes the product information and the physical address for the online retail platform to deliver a corresponding product to the physical address.
