#barion-nodejs

barion-nodejs is a compact Node.js module to manage online e-money and card payments via the Barion Smart Gateway. It allows you to accept credit card and e-money payments in just a few lines of code.

barion-nodejs lets you

• Start an online immediate or reservation payment easily
• Get details about a given payment
• Finish an ongoing reservation payment completely or partially, with automatic refund support
• Refund a completed payment transaction completely or partially

All with just a few simple pieces of code!

Installation

Using npm:

$ npm i -g npm
$ npm i --save barion-nodejs

In Node.js:

// Create barion object for the prod environment.
var barion = new (require('barion-nodejs'))();
// Create barion object for the test environment.
var barion = new (require('barion-nodejs'))(BarionTest);

// Import BarionError
var BarionError = barion.BarionError;

// Import the built-in requestbuilders
var BarionRequestBuilderFactory = barion.BarionRequestBuilderFactory;

Code Example

You can user the methods using simple Javascript objects and with the built-in request and object generators. We will give example for both.

Error handling

Money transfer

var moneySendOptionsWithObject = { UserName : "[email protected]", Password : "myweakpassword", Recipient : "[email protected]", Currency : "HUF", Amount : 100, Comment : "You are the best, pal!" };

barion.sendMoney(moneySendOptionsWithObject, function(err, data) { if(!err) { handleData(data); } else { handleError(err); } });

</details>

<details>
<summary>Send money using request builders</summary>
```javascript
var transferSendRequestBuilder =  new BarionRequestBuilderFactory.BarionTransferSendRequestBuilder();

var moneySendOptionsWithBuilder = transferSendRequestBuilder
    .setUsername("[email protected]")
    .setPassword("myweakpassword")
    .setRecipient("[email protected]")
    .setCurrency("HUF")
    .setAmount(100)
    .setComment("You are the best, pal!")
    .build();

barion.sendMoney(moneySendOptionsWithBuilder, function(err, data) {
    if(!err) {
        handleData(data);
    } else {
        handleError(err);
    }
});

Start payment

var paymentStartOptionsWithObject = { POSKey: "my_shops_pos_key_from_barion", PaymentType: "Immediate", GuestCheckOut: true, FundingSources: ["All"], PaymentRequestId: "request_id_generated_by_the_shop", Locale: "hu-HU", Currency: "HUF", Transactions: [ { POSTransactionId: "test_payment_id_from_shop", Payee: "[email protected]", Total: "1000", Items: [ { Name: "Test product", Description: "My favorite test product", Quantity: 1, Unit: "db", UnitPrice: 1000, ItemTotal: 1000 } ] } ] };

var item = itemBuilder
    .setName('Test product')
    .setDescription('My favorite test product')
    .setQuantity(1)

Refund a payment

var paymentRefundOptionsWithObject = { POSKey : "my_shops_pos_key_from_barion", PaymentId : "payment_id_in_the_barion_system", TransactionsToRefund : [ { TransactionId : "barion_transaction_id", POSTransactionId : "test_payment_id_from_shop", AmountToRefund : 10 } ]

    if (!err) {
        handleData(data);
