Welcome to the Web API documentation 👋

🌍 Learn how to build great integrations.

The Homey Web API is a HTTP + Socket.IO API to control devices, manage Flows etc. It is used by Athom for the Homey Mobile App, Homey Web App, Alexa, Google Assistant etc.

The Web API is also used by HomeyScript and apps using the homey:manager:api permission.

The Web API is not yet available to the public.
