Validating the access token

I actually have an example of such a service for app access tokens on github here

You mean, is this fine if I don’t validate app access token at all. I’m generating the new app access token 10 days before the expiration time and my service will generate the new app access token, if I get 4XX errors.

What is the error codes for InvalidTokenException and ExpiredTokenException?
