Harmony API

Better home experiences, together.

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:

  • Name
  • Company and website
  • Description of your app and how you'll incorporate Harmony
  • When you expect to have a working demo to share with us
  • (if known) The return URI we should send users to after OAuth with Harmony


We look forward to working with you.
The Logitech Harmony Team
