The next time you need to do something like this, take a look at https://github.com/openid/AppAuth-JS.

Here is an example which uses Node, and obtains your access tokens. (https://github.com/openid/AppAuth-JS/blob/master/src/node_ap...)

Once you have that - you can make any API requests by using the correct Authorization headers.

The author wanted to use Ruby. JS is out of context here

I think he meant as existing code you can pattern off of, not for direct inclusion.

The OAuth 2.0 Playground at https://developers.google.com/oauthplayground/ is another good resource for understanding refresh tokens and access tokens and how to get / exchange them.
