Consuming an REST API with Node.JS for a AWS Lambda Function

I just starting to learn how to develop Amazon Alexa Skills using the Alexa Skills Kit and AWS Lambda. I don't quite understand how to call an API and retrieve data from it. I found this template code from a Jordan Leigh video: 

var endpoint = ""; // ENDPOINT GOES HERE
var body = "";
https.get(endpoint, (response) => {
  response.on('data', (chunk) => body += chunk);
  response.on('end', () => {
    var data = JSON.parse(body);
    var subscriberCount = data.items[0].statistics.subscriberCount;
    context.succeed(
      generateResponse(
        buildSpeechletResponse(`Current subscriber count is ${subscriberCount}`, true),
        {}
      )
    );
  });
});

I understand that the endpoint variable will hold the url for the API, but I am unsure about the rest. In this code I believe he using a YouTube API for the current subscriber count. If I wanted to, for example, use the Dark Sky API to extract weather info, how would I go about this using this similar format?

Pretty much the same.

const https = require('https');
var body = "";

const url = "https://api.darksky.net/forecast/your-secret-key/37.8267,-122.4233"


var req = https.request(url, (res) => {

  res.on('data', (d) => {
    body += d;
  });

  res.on('end', () => {
       var data = JSON.parse(body);
       console.log("daily weather: ", data.daily);
  });


});

req.on('error', (e) => {
  console.error(e);
});

req.end();
