Abstract: The current document discloses methods and systems for providing extensions to web-services APIs, including RESTful APIs, and to extend other types of interfaces that define client/server-based distributed computing systems. The disclosed methods and systems are facilitated by, and include, respectively, a link registry within one or more server computers, or that is accessible to the one or more server computers, that together provide a web service accessed through an API. The link registry stores link-registry entries, each of which specifies one or more links to be added to response messages associated with a particular resource. The link registry, like any resource, is associated with a set of verbs, or functions, that allow entries to be added to, and removed from, the link registry and that allow entries to be modified. The link registry can be used both by server-resident functionality as well as by functionality within external computers to extend an existing web service or API.

Abstract: A system is described allowing a user to log into an API proxy by supplying login credentials and to have the API proxy log into the APIs of various web-based applications on behalf of the user by using the user's login credentials, without the user needing to separately log into each application. Calls made by the user to an application and application replies are routed through the API proxy. Further, the API proxy manages session expirations, e.g., by sending dummy calls to applications that exhibit idle expiration.
