Embedded extensions

Embedded extensions are the preferred choice for Mantle extensions, and are embedded directly into the layout of the Mantle application. They allow for richer integration with Mantle's navigation and provide a common look and feel of your application's layout and interactions.

At it's core: embedded extensions make use of the Mantle App Bridge to both authenticate their requests (session tokens) and a wrapped postMessage API for communicating between Mantle and your application.
