Israel,
Assuming that everything else is correct (I have no experience with GData) your post body should be something more like this : NSString *requestBody = @"status=somestatus"; Noting that the part after the '=' will need to be URL encoded as per the docs : http://dev.twitter.com/pages/auth#auth-request Otherwise twitter will not know what you are trying to do. You should also probably do the following rather than using NSASCII : [request setHTTPBody:[requestBody dataUsingEncoding:NSUTF8StringEncoding]] HTH On 15 Mar 2011, at 19:17, Israel Pasos wrote: > This is my first time with GData and I'm trying to use it with OAuth > to connect to Twitter and post status updates. > > Here's what I did: > > 1.
