Is there any way to check that access token is already generated for the particular user?

Explorer | Level 3

Hi,

I am using  dropbox java sdk for generating access token using oauth for a user and further i am using that access token to getting the file from dropbox to our project.But  the problem is that the token is generated every time the user logs in,which i am thinking is not a good way.Altough  old access token and new access token are working perfectly.

So is there any way in dropbox sdk to check that access token is already generated for the particular user?

The Dropbox API itself does not offer a way to check if any access tokens were already generated for a particular user.

You shouldn't need to do so anyway though. Once the app receives an access token, it should store and re-use that access token. Dropbox API access tokens don't expire by themselves so apps can re-use existing access tokens without sending the user through the authorization flow each time.

Exactly how you securely store and retrieve the access token is up to you though, and will depend on what kind of secure storage is available to your on your platform. In any case, the basic idea is that you should check your storage to see if you have an access token for the user already and use that, before prompting them to authorize the app if not.
