I was searching in the Facebook API documentation, but I can't find what I am looking for. So, what I am looking for is is there an API for creating your custom DO action. For example:
John Johson is riding a bike.
What I want is to send this 'riding' as a custom word coming from my app. And also 'bike' as a custom item as well. The other example I can think about is the running apps in Facebook. When you start to run and connect the app with your Facebook the app can say.
John Johson is running using Runtastic.
Thanks!
