The present invention provides a system and method for constructing a complete definition of a backend requirements model that can be automatically accessed and interpreted, and generated into a mobile consumable API for creation of, and use with, mobile applications. The mobile consumable API can be provided and made available to mobile app developers on a separate, stand-alone platform, and may act as an intermediary between the mobile app and the primary mainframe/enterprise/back end system. The method may include identification and definition of one or more of information providers, integration providers, and system behaviors, and creating a domain model. The domain model may be automatically codified into an API based solution as the app/mainframe interface, and stored on a development and operational platform for use.
