Is there any way to check if oauth token is expired or not?

Question

I am accessing web api using oauth token.

Token expires after 1 hour. But I want to add functionality to generate new token when it expires.

I found that in case of expired token it sends StatusCode as unauthorized.

Please let me know if its the only statuscode which tells about expiration of token.

The easiest way is to just try to call the service with it. It will reject it if it is expired and then you can request a new one.

You can also keep the time you received the token and use the expires_in to calculate when it will approximately expire. Then you request a new token before making a new request after the expiration date.
