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

// Initialize snap client object
// You can find it in Merchant Portal -> Settings -> Access keys
let snap = new midtransClient.Snap({
    isProduction : false,

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

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

// prepare Snap API parameter ( refer to: https://snap-docs.midtrans.com ) minimum parameter example:
