I am working in Facebook application in which I have created event Successfully, I am getting name.place, start_time, endtime property from api. But my problem is to send events invitation to Facebook friends, for this I am finding lot of details but that not help much.
Like you I have figured out how to create the event. However I am not sure how to get the event id. If you can tell me how to do that it would be great.
Bad news is it looks like Facebook has yet to implement the invite functionality using the Graph API.

Hope this helps.
