Answer 1

Modern problems require modern solutions:

const fetch = require('node-fetch');
const authUrl = "https://api-m.sandbox.paypal.com/v1/oauth2/token";
const clientIdAndSecret = "CLIENT_ID:SECRET_CODE";
const base64 = Buffer.from(clientIdAndSecret).toString('base64')

fetch(authUrl, { 
    method: 'POST',
    headers: {
        'Content-Type': 'application/json',
        'Accept': 'application/json',
        'Accept-Language': 'en_US',
        'Authorization': `Basic ${base64}`,
    },
    body: 'grant_type=client_credentials'
}).then(function(response) {
    return response.json();
}).then(function(data) {
    console.log(data.access_token);
}).catch(function() {
    console.log("couldn't get auth token");
});
