Hi ajay699patel,

At the beginning let's clarify that long lived access token is something obsolete and in spite an existing long lived access token (received some time ago) can still be used, issuing new such token is dropped already. Now all new access tokens are short lived and keep validity for 4 hours at most. There is new mechanism for long term access, without repeatable user authentication - refresh token. If you are using some of the Dropbox SDK's, there are examples (not all) that show how you can adapt your existing application or use them as a template for authentication' part for a new app. If you are performing direct calls to Dropbox servers (without any SDK), using only access token is no more possible for long term. You should extend your authentication procedure to use refresh mechanism. A simple example of such call sequence could be seen here. 😉

Hope this helps.
