Questions about token validation & refresh

Twitch suggest to validate the tokens on a regular interval, but this isn’t really possible in an application with many users (and many of them might be inactive). Is there an alternative? Like validating only before I make an API call?

Validating on a regular interval depends on your app and how validating is relevant to your implementation of the Twitch API. I do not disagree that what you describe is permissable.

@FullMetalBoy

What is exactly the meaning of a failed validation? Does it mean that the user canceled the authorization? Can it mean that the token expired (but the app is still authorized)?

Could be any of those things.

Twitch suggest that on a multi threaded app, you should refresh the token synchronously in order to avoid race conditions and the like. I agree. However, I have a hard time thinking of a good approach on how to do it. Anyone has a suggestion on this? My app uses Redis, if it’s any help.

Yes.
