This disclosure describes systems, methods, and computer-readable media related to mobile device purchase flows. In some embodiments, a mobile device may obtain a uniform resource identifier (URI). The mobile device may launch a browser based at least in part on the URI. The mobile device may submit a first set of data to a server based at least in part on the URI and receive a re-direct URI. The mobile device may launch an application in response to receiving the re-direct URI from the server, wherein the application submits a second set of data to the server. The mobile device may facilitate completion of a transaction by the application based at least in part on matching the first set of data and the second set of data at the server.
