node.js - Send email using Google API with only access token

Question

I want to send an email through Google API without the unnecessary OAUTH2 parameters. I only have the access_token and the refresh_token of that user.

How can I send an email through Gmail API through a basic POST request in NodeJS, with Request npm plugin?

abraham is correct, but I just thought I'd give you an example.

var request = require('request');

server.listen(3000, function () {
  console.log('%s listening at %s', server.name, server.url);

  // Base64-encode the mail and make it URL-safe 
  // (replace all "+" with "-" and all "/" with "_")
  var encodedMail = new Buffer(
        "Content-Type: text/plain; charset="UTF-8"
" +
        "MIME-Version: 1.0
" +
        "Content-Transfer-Encoding: 7bit
" +
        "to: [email protected]
" +
        "from: [email protected]
" +
        "subject: Subject Text

" +

        "The actual message text goes here"
  ).toString("base64").replace(/+/g, '-').replace(///g, '_');

  request({
      method: "POST",
      uri: "https://www.googleapis.com/gmail/v1/users/me/messages/send",
      headers: {
        "Authorization": "Bearer 'access_token'",
        "Content-Type": "application/json"
      },
      body: JSON.stringify({
        "raw": encodedMail
      })
    },
    function(err, response, body) {
      if(err){
        console.log(err); // Failure
      } else {
        console.log(body); // Success!
      }
    });
});

Don't forget to change the reciever and sender email address for the example to work.
