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!
Well, you’re a little too late on that one.
That used to be possible, it was called Custom Open Graph Actions - https://developers.facebook.com/docs/sharing/opengraph/custom
But those are now deprecated, you can not use them any more in new apps (and for existing ones, they will be removed within a year as well), see https://developers.facebook.com/docs/sharing/opengraph/custom-open-graph-deprecation
Now you can only use the built-in actions and objects, https://developers.facebook.com/docs/reference/opengraph
