Twitter App Card 403 error



I have been trying to use the App Card in my app. The card displays just fine but when I press “Tweet” I get the following error.

NSErrorFailingURLKey = “”;
NSLocalizedDescription = “Request failed: forbidden (403)”;
NSLocalizedFailureReason = “Twitter API error : Forbidden. (code 200)”;

I have checked the documents and didn’t find anything. I am using a valid TWTRSession because when I use it in the following request it works fine.
SLRequest *tweet = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodPOST URL:[@“” url] parameters:parameters];


Has your app been whitelisted by Twitter to post a Tweet containing an app card?

If not, then a 403 Forbidden is the expected response.
