I started researching this because I wanted to be able to delete a comment on the wall of a Facebook Event, because the \"Remove post\" doesn\'t seem to be applicable to com
You have a big problem with your urls :
https://graph.facebook.com/[POST_ID]?access_token=[ACCESS_TOKEN]?method=delete
Should be :
https://graph.facebook.com/[POST_ID]?access_token=[ACCESS_TOKEN] & method=delete
Identically,
https://graph.facebook.com/[POST_ID}?method=delete?access_token=[ACCESS_TOKEN]
should be :
https://graph.facebook.com/[POST_ID}?method=delete & access_token=[ACCESS_TOKEN]
So you have to use the ? before entering your parameters and then & between each parameter and the order should not have any importance ..
