Webhooks

To configure your webhooks URL, simply login Ping++ Dashboard, for more information, check out: docs

Code below shows how you can verify whether the webhooks you receive is sent by Ping++:

// Retrieve signature in header
$signature = $headers['X-Pingplusplus-Signature'] ?: null;

// Get the Ping++ RSA Public Key in Dashboard
$pub_key_contents = file_get_contents(__DIR__ . "/pingpp_rsa_public_key.pem");

if (openssl_verify(file_get_contents('php://input'), base64_decode($signature), $pub_key_contents, 'sha256')) {
    // Congrats! This request is from Ping++
    exit;
} 

http_response_code(400);

pingpp.js

The minimum integration for PC payment is simple, first you need to load pingpp.js , then test with code below:

<div class="app">
    <label><input id="amount" type="text" placeholder="金 额"/></label>
    <span class="up" onclick="wap_pay('upacp_pc')">银联网页支付</span>
    <span class="up" onclick="wap_pay('alipay_pc_direct')">支付宝网页支付</span>
    <span class="up" onclick="wap_pay('cp_b2b')">企业网银支付</span>
</div>

<script>
    function wap_pay(channel) {
        var amount = document.getElementById('amount').value * 100;
        var xhr = new XMLHttpRequest();
        xhr.open("POST", "http://localhost:8000/test.php", true);
        xhr.setRequestHeader("Content-type", "application/json");
        xhr.send(JSON.stringify({
            channel: channel,
            amount: amount
        }));
        xhr.onreadystatechange = function () {
            if (xhr.readyState == 4 && xhr.status == 200) {
                console.log(xhr.responseText);
                pingppPc.createPayment(xhr.responseText, function(result, err) {
                    console.log(result);
                    console.log(err.msg);
                    console.log(err.extra);
                });
            }
        }
    }
</script>

Test Mode

Pingpp accounts have test-mode API keys as well as live-mode API keys. These keys can be active at the same time. Data created with test-mode credentials will never hit the real payment channel networks and will never cost anyone money.

Unlike some gateways, there is no test mode endpoint separate to the live mode endpoint, the Pingpp API endpoint is the same for test and for live.

FAQ

Is it compatible with Ping++ official SDK?

Yes. It's 100% compatible with official API.

Why use omnipay-pingpp instead of Ping++ official SDK?

• It's simpler, more elegant, more consistantly designed 简单，优雅，一致的设计
• The implementation to the official API is more covered than SDK 对官方 API 的实现比 SDK 覆盖更多
• It's fully unit tested 完全的单元测试
• It's easier to switch between Chinese and other payment gateways (like Paypal) if you're running global business 国内国外支付网关的切换变得一致和流畅
• 你需要一个聚合了国内主流渠道的支付网关，并且希望它遵循一套合理的标准

Terminology

• transactionId is the Merchant’s reference to the transaction - so typically the ID of the payment record in the Merchant Site’s database. In Ping++, it's often called order_no.
• transactionReference is the Payment Gateway’s reference to the transaction. In Ping++, it's often called Charge Id, Red Envelope Id, Transfer Id.
• returnUrl is used by drivers when they need to tell the Payment Gateway where to redirect the customer following a transaction. Typically this is used by off-site ‘redirect’ gateway integrations. In Ping++, it's called differently by various payment channels.
• notifyUrl is used by drivers to tell the Payment Gateway where to send their server-to-server notification, informing the Merchant Site about the outcome of a transaction. In Ping++, it's called differently by various payment channels.
