Brick Pingback

Brick send asynchronous payment notification, pingback, as the additional confirmation of each payment as well.


Handle Pingback

On your server side, put the following code as an online server interface to interact with our Pingback:

<?php
require_once('/path/to/paymentwall-php/lib/paymentwall.php');
Paymentwall_Config::getInstance()->set(array(
    'api_type' => Paymentwall_Config::API_GOODS,
    'public_key' => 'YOUR_APPLICATION_KEY', // available in your Paymentwall merchant area
    'private_key' => 'YOUR_SECRET_KEY', // available in your Paymentwall merchant area
));

if ($pingback->validate(true)) {
    $productId = $pingback->getProduct()->getId();
    if ($pingback->isDeliverable()) {
        // deliver the product
    } else if ($pingback->isCancelable()) {
        // withdraw the product
    } else if ($pingback->isUnderReview()) {
        // set "pending" as order status

A pingback request typically contains all the information for you to do the product delivery. As an addition, Paymentwall provides a series of reversed parameters as custom pingback parameters for specific needs, you can also add your own parameters as custom pingback parameter in order to implement parameter transmission.

Below is a sample with default format:

Refer to pingback types for risk review of Brick payments.

After validating the pingback, your server is always expected to be able to proceed the delivery process and respond to it with only OK in the body of response.
