Paymentwall is the leading digital payments platform for globally monetizing digital goods and services. Paymentwall assists game publishers, dating sites, rewards sites, SaaS companies and many other verticals to monetize their digital content and services. Merchants can plugin Paymentwall's API to accept payments from over 100 different methods including credit cards, debit cards, bank transfers, SMS/Mobile payments, prepaid cards, eWallets, landline payments and others.
To sign up for a Paymentwall Merchant Account, click here.
This library allows developers to use Paymentwall APIs (Virtual Currency, Digital Goods featuring recurring billing, and Virtual Cart).
To use Paymentwall, all you need to do is to sign up for a Paymentwall Merchant Account so you can setup an Application designed for your site. To open your merchant account and set up an application, you can sign up here.
To install the library in your environment, you can download the ZIP archive, unzip it and place into your project.
Alternatively, you can run:
git clone git://github.com/paymentwall/paymentwall-php.git
Then use a code sample below.
Using Paymentwall PHP Library v2:
require_once('/path/to/paymentwall-php/lib/paymentwall.php');
Paymentwall_Config::getInstance()->set(array(
'api_type' => Paymentwall_Config::API_GOODS,
'public_key' => 'YOUR_PUBLIC_KEY',
'private_key' => 'YOUR_PRIVATE_KEY'
));Using Paymentwall PHP Library v1 (deprecated in v2):
require_once('/path/to/paymentwall-php/lib/paymentwall.php');
Paymentwall_Base::setApiType(Paymentwall_Base::API_GOODS);
Paymentwall_Base::setAppKey('YOUR_APPLICATION_KEY'); // available in your Paymentwall merchant area
Paymentwall_Base::setSecretKey('YOUR_SECRET_KEY'); // available in your Paymentwall merchant areaThe widget is a payment page hosted by Paymentwall that embeds the entire payment flow: selecting the payment method, completing the billing details, and providing customer support via the Help section. You can redirect the users to this page or embed it via iframe. Below is an example that renders an iframe with Paymentwall Widget.
$widget = new Paymentwall_Widget(
'user40012', // id of the end-user who's making the payment
'pw', // widget code, e.g. pw; can be picked inside of your merchant account
array( // product details for Flexible Widget Call. To let users select the product on Paymentwall's end, leave this array empty
new Paymentwall_Product(
'product301', // id of the product in your system
9.99, // price
'USD', // currency code
'Gold Membership', // product name
Paymentwall_Product::TYPE_SUBSCRIPTION, // this is a time-based product; for one-time products, use Paymentwall_Product::TYPE_FIXED and omit the following 3 array elements
1, // duration is 1
Paymentwall_Product::PERIOD_TYPE_MONTH, // month
true // recurring
)
),

echo $widget->getHtmlCode();The Pingback is a webhook notifying about a payment being made. Pingbacks are sent via HTTP/HTTPS to your servers. To process pingbacks use the following code:
