Based on Test Merchant Server
npm install github:perusworld/node-masterpass-api --saveThe v7 version is much simpler with just one call to get the lightbox and another to get payment data post lightbox.
To start the standard checkout in v7 is very simple, create a unique cartId for this purchase and associate it with this flow.
Start the lightbox on the client browser using the following include (depending upon stage or production) and the code
The callback url is something that you need to configure in you mastercard developer account settings, since the cartId needs to be associated to a specific flow you could do it statefull by storing it in your session or stateless by including it as a parameter in the callbackUrl below as the callback url needs to only match with that of the one configured at the top domain level. In this example case it could be somehting like http://localhost/requestTokenCallbackv7?cartId=some-unique-id

function beginCheckout(cartId, amount, callBackUrl, merchantCheckoutId) {
masterpass.checkout({
"cartId": cartId,
"amount": "" + Math.round(amount * 100),
"currency": 'USD',
"callbackUrl": callBackUrl,
"checkoutId": merchantCheckoutId,
"allowedCardTypes": ["master,amex,discover,visa"]
});
}Once the user goes though the lightbox and chooses the payment info, masterpass will redirect back to the callbackUrl, you can retrieve the user's payment credentials using
var async = require('async');
var masterpassapi = require('node-masterpass-api').masterpass();
var masterpass = new masterpassapi.Masterpass({

masterpass.paymentData({
oauthVerifier: req.query.oauth_verifier,
cartId: req.query.cartId //cart id from session or query param
}, (err, resp) => {

There is a sample app in the example folder that shows the available operations, set the following env variables before running the app.
$env:MP_PRIVATE_KEY = [IO.File]::ReadAllText("---your-private-key---")
$env:MP_CONSUMER_KEY = "---your-consumer-key---"
$env:MP_CALLBACK_URL = "http://localhost:3000/requestTokenCallbackv7"
$env:MP_ORIGIN_URL = "http://localhost:3000"
$env:MP_CHECKOUT_ID = "--your-merchant-checkout-id--"
$env:MP_ENV = "stage"Run the app
