TypeScript

import * as fs from 'fs';
import * as jwt from 'jsonwebtoken';

function getToken() {
var privateKey: Buffer = fs.readFileSync('./client_pos_dev_key.pem'); //provided

var terminal:any = {
  data:{
    ops: "auth",
    client_uuid: "483f797a-0e46-44de-a58f-5d5ea80ad7df", // provided
    terminal_id: "provided_terminal_id(s)" //provided
