const midtransClient = require('./../../index.js');
// const midtransClient = require('midtrans-client'); // use this if installed via NPM

// This is just for very basic implementation reference, in production, you should validate the incoming requests and implement your backend more securely.

// Initialize core api client object
// You can find it in Merchant Portal -> Settings -> Access keys
let core = new midtransClient.CoreApi({
    isProduction : false,
    serverKey : 'YOUR_SERVER_KEY',
    clientKey : 'YOUR_CLIENT_KEY'
});

// Alternative way to initialize core api client object:
// let core = new midtransClient.CoreApi();
// core.apiConfig.set({
//     isProduction : false,
//     serverKey : 'YOUR_SERVER_KEY',
//     clientKey : 'YOUR_CLIENT_KEY'
// })

// Another alternative way to initialize core api client object:
// let core = new midtransClient.CoreApi();
// core.apiConfig.isProduction = false;
// core.apiConfig.serverKey = 'YOUR_SERVER_KEY';
// core.apiConfig.clientKey = 'YOUR_CLIENT_KEY';

// IMPORTANT NOTE: You should do credit card get token via frontend using `midtrans-new-3ds.min.js`, to avoid card data breach risks on your backend
// ( refer to: https://docs.midtrans.com/en/core-api/credit-card?id=_1-getting-the-card-token )
// For full example on Credit Card 3DS transaction refer to:
// (/examples/expressApp) that implement Snap & Core Api

// prepare CORE API parameter to get credit card token
// another sample of card number can refer to https://docs.midtrans.com/en/technical-reference/sandbox-test?id=card-payments
