In Google Apps Script, you can use the Advanced Gmail Service without needing to fuss with the Web API directly. Remember, the service must be enabled before use.

/**
 * Send a raw RFC 2822 formatted and base64url encoded email
 * using the Advanced Gmail service.
 *
 * From http://stackoverflow.com/a/35073785/1677912
 *
 * @param {String}  raw  RFC 2822 formatted and base64url encoded message
 *
 * @returns {String}     Message ID of the message (now in Sent Messages).
 */
function sendRawMessage( raw ) {
  var message = Gmail.newMessage();
  message.raw = raw;
  var sentMsg = Gmail.Users.Messages.send(message, 'me');
  return sentMsg.id;
}
