I have an app that used to create events on Facebook through the API when users organised them. [create event was removed from the API in v2.0][1]

Can anyone suggest a good event app that:

1) allows events to be created by API
2) lets users join event very easily with Facebook, Twitter and/or Google account
3) allows events to be shared very visibly on FB, etc.

In sum, I want a slick replacement to events that I can make from my app! Please help..
