How to Validate OAuth 2.0 Access Token

[Anonymous]

Hi

I have successfully connected to Rest API and received OAuth 2.o access token which is valid only for 60min. When the token expires I will need to generate the new access token. Please tell me how to validate the access token?  

Thanks in advance

Or you can be in loop to get new token using tloop, loop stars every 60 min or finish of your process.
