Using the access token with the SkyDrive API - api

Question

I have been trying to get access to the json result with the following link:
https://apis.live.net/v5.0/file.a4423f3123801749.A4423F3123801749!418
But as you can see by clicking on it yourself, you need an access token.
I already have an access token, but it only lasts for 3600 seconds (1 hour).
Is there a way to get the results of the link (the json shown below) without the access token expiring? I know there is a refresh token, but I am unsure how to use it.

Do a post to https://login.live.com/oauth20_token.srf to convert your refresh_token to an access_token. Read more in MS documentation bullet #6.
Here are a sample node.js code
var options,request;
request = require('request');
options = {
url: 'https://login.live.com/oauth20_token.srf',
form: {
client_id: YOUR CLIENT_ID,
redirect_uri: YOUR REDIRECT_URI,
client_secret: YOUR CLIENT_SECRET,
refresh_token: YOUR REFRESH_TOKEN,
grant_type: 'refresh_token'
},
headers: {
'Accept': 'application/json'
}
};
request.post(options, function(err, response, data) {
});
