tvOS - How to auth user via REST API?

Hey guys,

is there way how to authentificate user via 3th party REST API? For example, If I will want to use Dribbble API, but for likes you need be logged. Is there way how to do it without iOS/OSX app? Just via tvOS app and JS server?

I can’t found example etc.

Thanks for all tips, I will be really glad if you will help me with the way!
