` I am trying to uplaod video file to the specified url of twit pic which helps the user to upload their videos to twitter. When i press button video file should upload into the url which i used. but when i check,getting a response that the page you requested could not be found.Has anyone tried to upload videos to twit pic. Please give me some sample codes.Thanks in advance.

Answer 1

the error is related to the incorrect urlString. I also dont see which twitpic-api-version you are using.

twitpic-api-version-2 (latest api-version this should be used) needs authorization first via OAuth and api-key, message and media as parameters
urlString should look like: http://api.twitpic.com/2/upload.xml

twitpic-api-version-1 (not the latest one: only there because of compability. Will be shut down sometime in future) needs the parameters you added but also two additional oauth-parameter which are missing in your body.
urlString should look like: http://api.twitpic.com/1/upload.xml
