A method beginning with adding new resource to an enterprise system. Responsive to adding, an API builder executed by the computer automatically builds a new API exclusively for the new resource. The new API is configured to manage communications between the new resource and the proxy server based on a context resource identifier provided by the API builder and stored in an identifier data structure. The context resource identifier is to be provided to the gateway in response to a request from the client to access the new resource using a uniform resource identifier that identifies to the new resource. The context resource identifier is static over time within the enterprise. A proxy server uses the context resource identifier to call the new API in order to access the new resource, whereby a speed of communication between the client and the new API is increased.
