G2A PAY - PHP API

Complex PHP5 CURL library. See also official documentation: https://pay.g2a.com/documentation#introduction

Great features of the library:

• Get payment detail
• Set discount
• Easily add item to order
• Verify IPN hash

Install (Composer):

composer require tuks128/g2a-pay-php5-api

Initialization:

<?php

use Tuxxx128\G2aPay\G2aPayApi;
use Tuxxx128\G2aPay\G2aPayItem;

$g2aPayApi = new G2aPayApi('API HASH', 'SECRET KEY', true, 'EMAIL OF STORE');

Boolean type in construction determines mode of environment production (true) or development (false).

Add new item to order list:

<?php

$item = (new G2aPayItem)->itemTemplate();

$item->name = "My item";
$item->url = "http://...";
$item->price = 10; // default currency is 'EUR'

$g2aPayApi->addItem($item);

Set discount (percents or fixed amount):

<?php

$item = (new G2aPayItem)->itemTemplate();

$item->name = "Discount";
$item->url = "http://...";

Set over percent:

$g2aPayApi->addPercentDiscountItem($item, 25); // 25% from total amount

Or you can set directly fixed amount:

$g2aPayApi->addAmountDiscountItem($item, 5); // 5 EUR

Change default currency:

The function is not calculating..

<?php

$g2aPayApi->setCurrency("USD"); // from default currency 'EUR' to 'USD'

Create new payment:

<?php

$g2aPayApi->setUrlFail("http://..");
$g2aPayApi->setUrlSuccess("http://..");
$g2aPayApi->setOrderId(ORDER ID);
// $g2aPayApi->setEmail('[email protected]');

header('Location: '.$g2aPayApi->getRedirectUrlOnGateway());

Get complete transaction detail

<?php

$transactionDetail = $g2aPayApi->getPaymentDetailById($transactionId);

var_dump($transactionDetail);
