Harmony API

Using the Harmony API, companies such as SmartThings, IFTTT, Yonomi, Misfit and others give their users access to personalized Harmony Activities such as Welcome Home, Watch a Movie, or Listen to Music directly within their own devices and services. Together, we are creating simpler, more powerful and more comprehensive smart home experiences.

View our online API documentation. The current version of our API allows you to start and stop Harmony Activities, but doesn't currently grant access to control volume, play/pause, channel selection, nor to integrate control of your product from the Harmony remote. You may either request access to our current API, or sign up for our mailing list to be notified when future enhancements become available.

For access, please provide:

• First and last name
• If a company, your proper name and website
• Description of your app and how you'll incorporate Harmony
• The return URI we should send users to after OAuth (mandatory)
  — see Redirect Endpoint in our documentation

We look forward to working with you.
