Web Introducer

An Introducer enables Web content to discover a user's personal resources, no matter where they are hosted, and gain permission to interact with them via a one-click user interaction.

For example, a Web page can use an Introducer to discover a user's personal link sharing service and send it a link. Using the Introducer for these types of interactions has many advantages over other approaches.

The Introducer supports custom sharing interactions between Web sites and so can be adapted to support your application's sharing needs.
