Do I need publish_stream scope to delete invitation requests? - facebook-graph-api

Question

I'm using FB.ui({method: 'apprequests', ... }) to let users invite their friends to my java web app.
In the Facebook Requests Dialog documentation it says that I need to delete the request when the user has accepted the request:
When a user is directed to your application, by clicking a Request
from the application, the games dashboard, or from a Request
notification, you must delete the request after it has been accepted.
Requests are not automatically deleted once they have been clicked,
thus it is the developer’s responsibility to clear them once they have
been consumed.
http://developers.facebook.com/docs/reference/dialogs/requests/#deleting
When I try to do this with the RestFB Graph API Java client I get a permission error from facebook.
The code:
FacebookClient client = new DefaultFacebookClient(appAccessToken, new DefaultWebRequestor(), new DefaultJsonMapper());
client.deleteObject(String.format("%d_%d", requestId, facebookUserId));
The log says:
(com.restfb.DefaultWebRequestor) INFO: Executing a POST to
graph.facebook.com/XXX_XXX with parameters (sent in request body):
method=delete&access_token=XXX&format=json&locale=en_US
The error:
Facebook responded with HTTP status code 403 and response body:
{"error":{"message":"(#200) Permissions
error","type":"OAuthException"}}
I have tried both app access token and receiving user's access token, and I have scopes email and publish_actions. I read somewhere that I may need the publish_stream scope. I would rather not ask my users for that just to be able to delete requests, though? Or is it something else I'm doing wrong?

You don't need the publish_stream scope if you use the APP Token.
If you use the C# facebook SDK you can use this:
var fb = new FacebookClient(Config.FacebookAppId, Config.FacebookAppSecret);
var result = fb.Delete(string.Format(
"{0}_{1}?access_token={2}",
facebookRequestId,
facebookUserId,
fb.AccessToken
));
