PAYDUNYA NodeJS API Client

The Node.JS library for PAYDUNYA (paydunya.com).

Built on the PAYDUNYA HTTP API (beta).

Installation

npm install --save paydunya

API configuration

Setup paydunya API keys.

var setup = new paydunya.Setup({
  masterKey: 'wQzk9ZwR-Qq9m-0hD0-zpud-je5coGC3FHKW',
  privateKey: 'test_private_rMIdJM3PLLhLjyArx9tF3VURAF5',
  publicKey: 'test_public_kb9Wo0Qpn8vNWMvMZOwwpvuTUja-OSDNhUqKoaTI4wc',
  token: 'IivOiOxGJuWhc5znlIiK',
  mode: 'test' // optional. use in sandbox mode.
});

It might usually be suitable to put your API configuration in environment variables. In that case you can initialize paydunya.Setup without passing configuration parameters. The library will automatically detect the environment variables and use them. Auto-detected environment variables: PAYDUNYA_MASTER_KEY, PAYDUNYA_PRIVATE_KEY, PAYDUNYA_PUBLIC_KEY, PAYDUNYA_TOKEN

Checkout Store Configuration

var store = new paydunya.Store({
  name: 'Magasin Chez Sandra', // only name is required
  tagline: "L'élégance n'a pas de prix",
  phoneNumber: '336530583',
  postalAddress: 'Dakar Plateau - Etablissement kheweul',
  logoURL: 'http://www.chez-sandra.sn/logo.png'
});

Initialize Checkout Invoice

var invoice = new paydunya.CheckoutInvoice(setup, store);

Initialize Onsite Invoice

var invoice = new paydunya.OnsiteInvoice(setup, store);

Add Invoice Items & Description

invoice.addItem('Ordinateur Lenovo L440', 1, 400000, 400000); // name, quantity, unit price, total price
invoice.description = 'Lenovo Product'

Setting Total Amount Chargeable

invoice.totalAmount = 400000;

Redirecting to paydunya Checkout

After setting total amount and adding items to your invoice you can create a checkout and redirect the customer. It takes a callback which gets passed the updated invoice object containing the url.

invoice.create()
  .then(function (){
    invoice.status;
    invoice.token; // invoice token
    invoice.responseText;
    invoice.url; // PAYDUNYA redirect checkout url
  })
  .catch(function (e) {
    console.log(e);
  });

Onsite Payment Request (OPR): Step 1 - Token request

After setting total amount and adding items to your invoice get the paydunya customer's username or phone number and start an OPR request.

invoice.create('[email protected]')
  .then(function(){
    invoice.oprToken; // You need to pass the OPR Token on Step 2
    invoice.token; // invoice token
    invoice.responseText;
  })
  .catch(function (e) {
    console.log(e);
  });

Onsite Payment Request (OPR): Step 2 - Charge

To successfully complete an OPR charge, you need both your OPR Token & the Confirmation code sent to the customer. After a successfull charge you can programatically access the receipt url, customer information and more.

invoice.charge('oprToken', '0000')
  .then(function (){
    invoice.status;
    invoice.responseText;
    invoice.receiptURL;
    invoice.customer; // {name: 'Alioune Badara', phone: '773830279', email: '[email protected]'}
  })
  .catch(function (e) {
    console.log(e);
  });

Extra API methods

Adding Tax Information

You may include tax information on on the checkout page. This information will be available on the invoice & receipt printouts and PDF downloads.

invoice.addTax('VAT (18%)', 3000);
invoice.addTax('Autre taxe (5%)', 200);

Adding Custom Data

There are times when you may need to add an extra load of data with the checkout information for later use. paydunya allows saving of custom data on their servers which are persisted even after successful payment. Note: Custom data is not displayed anywhere on the checkout page, invoice/receipt download & printouts.

invoice.addCustomData('CartID', 32393);
invoice.addCustomData('Plan', 'NOEL');

Setting a Cancel URL

You can optionally set the URL where your customers will be redirected to after canceling a checkout. Note: There are two options as to how the cancel URL is set, one is to set it globally using the checkout setup information and the other is set it as per checkout invoice. Setting the cancel URL directly on the invoice instance will overwrite the global settings if already set.

// Globally
var store = new paydunya.Store({
  name: 'Magasin chez Sandra',
  cancelURL: 'http://www.ma-super-boutique.com/'
});

// Per Checkout
invoice.cancelURL = 'http://www.ma-super-boutique.com/';

Setting a Return URL

PAYDUNYA does a good job of managing receipt downloads and printouts after your customer successfuly makes payment. However there may be cases where you may descide to redirect your customers to another URL after successfully making payment. Return URL guarantees this action. Note: PAYDUNYA will append ?token=INVOICE_TOKEN to your URL.

// Globally
var store = new paydunya.Store({
  name: 'Magasin chez Sandra',
  returnURL: 'http://www.ma-super-boutique.com/confirm'
});

// Per Checkout
invoice.returnURL = 'http://www.ma-super-boutique.com/confirm';

Confirming a Checkout Programatically

The API allows you to check on the status of any checkout using the checkout token key. You have access to all the data including the receipt download link & customer information in cases where the checkout has been confirmed as completed.

var token = 'odaff0a023';

var invoice = new paydunya.CheckoutInvoice(setup, store);

invoice.confirm(token)
  .then(function (){
    invoice.status; //  completed, pending, canceled or fail
    invoice.responseText;

    // available if status == 'completed'
    invoice.customer; // {name: 'Alioune Badara', phone: '772639273', email: '[email protected]'}
    invoice.receiptURL; // 'https://app.paydunya.com/sandbox-checkout/receipt/pdf/test_44a6fef19a.pdf'
  })
  .catch(function (e) {
    console.log(e);
  });

DirectPay

You can pay any paydunya account directly via your third party apps. This is particularly excellent for implementing your own Adaptive payment solutions on top of paydunya.

var directPay = new paydunya.DirectPay(setup);
directPay.creditAccount('[email protected]', 5000)
  .then(function (){
    directPay.description;
    directPay.responseText;
    directPay.transactionID;
  })
  .catch(function (e) {
    console.log(e);
  });

Running Tests

To run tests just setup the API configuration environment variables. An internet connection is required for some of the tests to pass.

npm install -g mocha

Then npm test or mocha
