Best way to know if a token is still valid?

Question

Hi all, i look into API docs endpoints, and i can't find out the correct way to establish if a token is still valid or not. Or better i could but a suggestion maybe is best ...

I mean this: on an user interface, the generated token is shown to user when he load his profile. Than i would like know before than the page load, if the token is active or not. Since no curl call is done on profile, except when the user click to request/generate a new token, when user load page, i could arbitrary do a curl call to check if error come out, and establish if the token is still valid, or has been maybe revoked by user via/into dropbox.com account.

What the best way?

I've not read something about somewhere (as this is very probably due to my Eng) maybe.

Thank you!

The best way to check if an access token is still valid with the Dropbox API is just to make a call and check the response. For example, a simple call with no side effects such as /2/users/get_current_account is a good one for this.
