App to setup automatic tweets when the user logging into our webpage using Twitter credentials


We have a platform similar than TwitCam, we setup everything to allow users login into our platform using twitter and Facebook credentials.

With the Facebook connect we got the same functionality as TwitCam, when a user login using Facebook Credentials, the system generate a Post into his Facebook Account, when the user start a conversation into the Chat the system share the conversation into Facebook, allowing the user promoted his EShowsCam.

But when we try to do the same with the Twitter Connect we can’t, well the app allow user login with twitter credentials but not any tweet is generate.

can some one explain us what we need to do to allow the platform share a tweet when they login or when they start a conversation in the chat?
