Methods and system for interface data utilization are described. In one embodiment, source interface data may be provided from a provider. The source interface data may be capable of being used to provide a source user interface for a networked resource associated with the provider. A user request may be received through the source user interface. A service call may be provided over a network to an application based on the receiving of the user request. The application may be associated with an application manager. Response data may be received over the network from the application based on the service call. Target interface data may be rendered based on the response data. The target interface data may be provided from the provider.
