README

A Payum gateway to use SystemPay (a French payment system)

Latest Stable Version Build Status

Requirements

Installation

$ composer require yproximite/payum-system-pay

Configuration

With PayumBundle (Symfony)

First register the gateway factory in your services definition:

# config/services.yaml or app/config/services.yml
services:
    yproximite.system_pay_gateway_factory:
        class: Payum\Core\Bridge\Symfony\Builder\GatewayFactoryBuilder
        arguments: [Yproximite\Payum\SystemPay\SystemPayGatewayFactory]
        tags:
            - { name: payum.gateway_factory_builder, factory: system_pay }

Then configure the gateway:

# config/packages/payum.yaml or app/config/config.yml

payum:
  gateways:
    system_pay:
      factory: system_pay
      vads_site_id: 'change it' # required 
      certif_prod: 'change it' # required 
      certif_test: 'change it' # required 
      sandbox: true

With Payum

<?php
//config.php

use Payum\Core\PayumBuilder;
use Payum\Core\Payum;

/** @var Payum $payum */
$payum = (new PayumBuilder())
    ->addDefaultStorages()

    ->addGateway('gatewayName', [
        'factory'      => 'system_pay',
        'vads_site_id' => 'change it',
        'certif_prod'  => 'change it',
        'certif_test'  => 'change it',
        'sandbox'      => true,
    ])

    ->getPayum()
;

Usage

Make sure your Payment entity overrides getNumber() method like this:

<?php

namespace App\Entity\Payment;

use Doctrine\ORM\Mapping as ORM;
use Payum\Core\Model\Payment as BasePayment;

/**
 * @ORM\Table
 * @ORM\Entity
 */
class Payment extends BasePayment
{
    /**
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="IDENTITY")
     *
     * @var int
     */
    protected $id;

    /**
     * {@inheritdoc}
     */
    public function getNumber()
    {
        return (string) $this->id;
    }
}

By doing this, the library will be able to pick the payment's id and use it for the payment with System Pay (we should send a transaction id between 000000 and 999999).

Payment in several instalments

If you planned to support payments in several instalments, somewhere in your code you will need to call Payment#setPartialAmount to keep a trace of the amount per payment:

<?php
class Payment extends BasePayment
{
    // ...

    /**
     * @ORM\Column(type="integer", nullable=true)
     */
    protected $partialAmount;

    public function getPartialAmount(): ?int
    {
        return $this->partialAmount;
    }

    public function setPartialAmount(?int $partialAmount): void
    {
        $this->partialAmount = $partialAmount;
    }
}

Usage

<?php

use App\Entity\Payment;
use Yproximite\Payum\SystemPay\Api;
use Yproximite\Payum\SystemPay\PaymentConfigGenerator;

// Define the periods
$periods = [
    ['amount' => 1000, 'date' => new \DateTime()],
    ['amount' => 2000, 'date' => (new \DateTime())->add(new \DateInterval('P1M'))],
    ['amount' => 3000, 'date' => (new \DateTime())->add(new \DateInterval('P2M'))],
];

// Compute total amount
$totalAmount = array_sum(array_column($periods, 'amount'));

// Compute `paymentConfig` fields that will be sent to the API
// It will generates something like this: MULTI_EXT:20190102=1000;20190202=2000;20190302=3000
$paymentConfig = (new PaymentConfigGenerator())->generate($periods);

// Then create payments
$storage = $payum->getStorage(Payment::class);
$payments = [];

foreach ($periods as $period) {
    $payment = $storage->create();
    $payment->setTotalAmount($totalAmount);
    $payment->setPartialAmount($period['amount']);

    $details = $payment->getDetails();
    $details[Api::FIELD_VADS_PAYMENT_CONFIG] = $generatedPaymentConfig;
    $payment->setDetails($details);

    $storage->update($payment);
    $payments[] = $payment;
}
