I want to know the validity of the Access Token and also what is the duration of time to that Token will expire. Because in my case, initially i get the oauth_token and oauth_verifier and also i am getting the Access Token , but while posting the tweet, its not posting. Its showing Bad Request Error and sometimes its showing Unauthorized Error. In this case i am saving the Consumer key, Secret Key and also the Access token in the system and using when
ever i want.
