Installation

This SDK uses composer.

Composer is a tool for dependency management in PHP. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you.

For more information on how to use/install composer, please visit: https://github.com/composer/composer

To install the Pay.nl PHP sdk into your project, simply

$ composer require paynl/sdk

Installation without composer

If you don't have experience with composer, it is possible to use the SDK without using composer.

You can download the zip on the projects releases page.

1. Download the package zip (SDKvx.x.x.zip).
2. Unzip the contents of the zip, and upload the vendor directory to your server.
3. In your project, require the file vendor/autoload.php
4. You can now use the SDK in your project

Requirements

The PAY. PHP SDK is tested up to PHP version 8.2 and requires the PHP cURL extension.

# Save this transactionid and link it to your order

On the exchange script, process the order

# Optionally you can send a message after TRUE|, you can view these messages in the logs.
# https://admin.pay.nl/logs/payment_state
echo ($transaction->isPaid() || $transaction->isAuthorized())?'Paid':'Not paid';

Failover gateway

In the event of an outage, set the failover gateway like this:

use Paynl\Config;
use Paynl\Transaction;

require __DIR__ . '/vendor/autoload.php';

Config::setTokenCode('AT-####-####');
Config::setApiToken('****************************************');
Config::setServiceId('SL-####-####');

# Setting Failover gateway (for available cores, call Config::getCores())
Config::setCore( Config::CORE2 );

# Or for SDK versions lower then 1.6.7, use:
Config::setApiBase('https://rest.achterelkebetaling.nl');

$requiredArguments = []; // See: Start a transaction example
$result = Transaction::start($requiredArguments);

Testing

Please run vendor/bin/phpunit --bootstrap vendor/autoload.php tests/ to test the application
