PayPal Plus - Webhook - 用于更改数据库中的付款状态

Question

如果我的 Opencart 商店客户使用 PayPal 进行支付，我需要一个 Webhook 来控制付款变化，如待定、退款等。

因此，如果客户使用 PayPal 进行支付，则从 PayPal Plus 通过 Webhook URL 调用以下方法：

public function webhook(){

    $token = $this->getToken();

    $mode = ".sandbox";

    $ch = curl_init();

    $header = array('Content-Type: application/json', 'Authorization:Bearer'.$token);

    curl_setopt($ch,  CURLOPT_HTTHEADER, $headers);

    curl_setopt($ch, CURLOPT_URL, "https://api".$mode."paypal.com/v1/notification/webhooks/");

    curl_setopt($ch,  CURLOPT_HEADER, false);
    curl_setopt($ch,  CURLOPT_SSL_VERYFYPEER, false);
    curl_setopt($ch,  CURLOPT_CUSTOMREQUEST, 'GET');
    curl_setopt($ch,  CURLOPT_RETURNTRANSFER, true);

    $result = curl_exec($ch);

    $json = json_decode($result);
}

目前我需要的是当前交易ID和新的付款状态，以便更新我的数据库中的值。

有人能告诉我如何在“webhook”方法中获取这些参数吗？

print_r($result) 是什么？ - Prince Adeyemi

嗨，我已将结果添加到文本中。我不知道如何从最后一次付款中获取transaction_id和付款状态。 - Nils

不要主动调用！等待调用并处理。

public function webhook() {
    $body = file_get_contents('php: //input');

    $data = json_decode($body, true);

    //Validate and verify webhook here.

    if ($data['event_type'] == 'PAYMENT.AUTHORIZATION.CREATED') {
        //Payment authorization created.
    } else if ($data['event_type'] == 'PAYMENT.AUTHORIZATION.VOIDED') {
        //Payment authorization voided.
    } else if ($data['event_type'] == 'PAYMENT.CAPTURE.COMPLETED') {
        //Payment capture completed.
    } else if ($data['event_type'] == 'PAYMENT.CAPTURE.DENIED') {
        //Payment capture denied.
    } else if ($data['event_type'] == 'PAYMENT.CAPTURE.PENDING') {
        //Payment capture pending.
    } else if ($data['event_type'] == 'PAYMENT.CAPTURE.REFUNDED') {
        //Payment capture refunded.
    } else if ($data['event_type'] == 'PAYMENT.CAPTURE.REVERSED') {
        //Payment capture reversed.
    } else {
        //Handle other webhooks
    }
}

Answer 2

获取所需的数据很容易。

您正在调用PP，json_encoded变量（$json）是结果。

现在您可以访问这些值，例如：

$webhooks[0]->id

但是要获取所需的数据（这里是交易 ID 和新状态），您使用了错误的调用。

payment/payments/PAYMENT_ID

这是您所需的服务。
