Now that we have announced two major features to our platform: links and location, smart developers from all around the world can leverage them into creating useful and amazing uses for the Yo platform using the Yo API.

The goal of this challenge is to get developers to discover the power of our simple platform and build on it.

Check out our API documentation website and our branding guidelines.

Some APIs to ignite your imagination:

Why not make money out of your submission? Create a website that allows users to enter their information and trigger things just with one tap, Yo. (See example)

For examples of existing API integrations check out the Yo Index


 Anyone can participate.


  • Submissions needs to be a tested, working, production-grade Yo service, that Yo users can already use in their Yo app.
  • A mini-website that shows the service and explains how to use it and will be linked if and when the service will appear in the Yo Index.
