Nets Easy PHP bindings

CircleCI License

The NETS Easy PHP library provides convenient access to the NETS Easy API from applications written in the PHP language. It includes a pre-defined set of classes for API resources that initialize themselves dynamically from API responses.

Requirements

PHP 7.3.0 and later.

Composer

You can install the bindings via Composer. Run the following command:

composer require apility/nets-easy

To use the bindings, use Composer's autoload:

require_once('vendor/autoload.php');

Getting Started

Simple usage looks like:

Backend integration

<?php

use Nets\Easy;
use Nets\Easy\Payment;

Easy::setup([
  'secret_key' => '00000000000000000000000000000000',
  'checkout_key' => '00000000000000000000000000000000',
  'merchant_id' => '000000000'
]);

$payment = Payment::create([
  'checkout' => [
    'url' => 'https://domain.tld/checkout',   // The exact URL where your checkout is hosted (except query parameters and fragments)
    'termsUrl' => 'https://domain.tld/terms', // Your terms
  ],
  'order' => [
    'currency' => 'NOK',
    'reference' => '1',            // A unique reference for this specific order
    'amount' => 10000,              // Total order amount in cents
    'items' => [
      [
        'reference' => '1',        // A unique reference for this specific item
        'name' => 'Test',
        'quantity' => 1,
        'unit' => 'pcs',
        'unitPrice' => 8000,        // Price per unit except tax in cents
        'taxRate' => 25000          // Taxrate (e.g 25.0 in this case),
        'taxAmount' => 2000         // The total tax amount for this item in cents,
        'grossTotalAmount' => 10000 // Total for this item with tax in cents,
        'netTotalAmount' => 8000    // Total for this item without tax in cents
      ]
    ]
  ]
]);

Frontend integration

The simplest way to integrate the checkout form in the frontend, is to use the form helper method on the Payment object.

<?php

use Nets\Easy;
use Nets\Easy\Payment;

Easy::setCredentials(...);

$payment = isset($_GET['paymentId']
  ? Payment::retrieve($_GET['paymentId'])
  : Payment::create(...);

$form = $payment->form([
  'redirect' => 'https://domain.tld/checkout/complete', // URL to redirect to on payment completion (paymentId query parameter is appended)
  'theme' => [ // Optional
    'textColor' => 'blue',
    'linkColor' => '#bada55',
    'buttonRadius' => '50px'
  ]
]);

?>
<div id="easy-complete-checkout"></div>
<?php echo $form; ?>

Alternatively, if you require full control of checkout flow, implement it manually:

<html>
  <head>
    <title>Example checkout</title>
  </head>
  <body>
    <div id="easy-complete-checkout"></div>
    <script>
      document.addEventListener('DOMContentLoaded', () => {
        const checkout = new Dibs.Checkout({
          checkoutKey: "00000000000000000000000000000000", // Checkout Key
          paymentId: "00000000000000000000000000000000", // Payment ID created in the backend integration
          partnerMerchantNumber: "000000000", // Merchant ID
          containerId: "easy-complete-checkout", // Container element where the checkout form should be created
        })

        checkout.on('payment-completed', ({ paymentId }) => {
          // Payment is completed, do what you need to do here
        })
      })
    </script>
    <script src="https://test.checkout.dibspayment.eu/v1/checkout.js?v=1"></script>
    <!-- or if in production: -->
    <script src="https://checkout.dibspayment.eu/v1/checkout.js?v=1"></script>  </body>
</html>
