Quick and easy Smarty address validation.

const SmartySDK = require("smartystreets-javascript-sdk");
const SmartyCore = SmartySDK.core;
const Lookup = SmartySDK.internationalAddressAutocomplete.Lookup;

// for Server-to-server requests, use this code:
// let authId = process.env.SMARTY_AUTH_ID;
// let authToken = process.env.SMARTY_AUTH_TOKEN;
// const credentials = new SmartyCore.StaticCredentials(authId, authToken);

// for client-side requests (browser/mobile), use this code:
const key = process.env.SMARTY_EMBEDDED_KEY;
const credentials = new SmartyCore.SharedCredentials(key);

// The appropriate license values to be used for your subscriptions
// can be found on the Subscription page of the account dashboard.
// https://www.smarty.com/docs/cloud/licensing
