App-to-App interaction APIs - one more time, with feeling

Hey WebAppers,

Just ran into this dragon for the 1,326th time, so thought I would do a write-up to rekindle discussion on this important area of developer need the platform currently fails to address: http://www.backalleycoder.com/2015/10/13/app-to-app-interaction-apis/. We have existing APIs/specs that get relatively close, and my first instinct would be to leverage those and extend their capabilities to cover the broader family of use-cases highlighted in the post.

I welcome your ideas, feedback, and commentary,

- Daniel
