Halcyon™ uses an open JSON REST API. 

We will update this page when the Halcyon Lighting API is published. If you wish to share your ideas about what you would do with the Halcyon API, then visit our Forum and use the developers discussion board.

If you are interested in becoming one of a very small, restricted number of early developers and having early access to the lighting API (upon signing an NDA) then please email with a brief description of your project.
