By following the guide on https://developer.paypal.com/webapps/developer/docs/integration/web/accept-paypal-payment/ , I have successfully created a payment and redirect the user to approve it.

The created payment is something look like bellow, and I save it in user's session for further reference. 

{
  "id": "PAY-6RV70583SB702805EKEYSZ6Y",
  "create_time": "2013-03-01T22:34:35Z",
  "update_time": "2013-03-01T22:34:36Z",
  "state": "created",
  "intent": "sale",
  "payer": {
    "payment_method": "paypal"
  },
  "transactions": [
    {
      "amount": {
        "total": "7.47",
        "currency": "USD",
        "details": {
          "subtotal": "7.47"
        }
      },
      "description": "This is the payment transaction description."
    }
  ],
  "links": [
    {
      "href": "https://api.sandbox.paypal.com/v1/payments/payment/PAY-6RV70583SB702805EKEYSZ6Y",
      "rel": "self",
      "method": "GET"
    },
    {
      "href": "https://www.sandbox.paypal.com/webscr?cmd=_express-checkout&token=EC-60U79048BN7719609",
      "rel": "approval_url",
      "method": "REDIRECT"
    },
    {
      "href": "https://api.sandbox.paypal.com/v1/payments/payment/PAY-6RV70583SB702805EKEYSZ6Y/execute",
      "rel": "execute",
      "method": "POST"
    }
  ]
}

After user approved the payment, Paypal will redirect the user to the return_url. For example, http://<return_url>?token=EC-60U79048BN7719609&PayerID=7E7MGXCWTTKK2.

In order to execute the payment, a POST request has to made to https://api.sandbox.paypal.com/v1/payments/payment/{payment_id}/execute/.

Question

The only two pieces of information provided from Paypal in the URL is token and PayerID. How can I find the corresponding payment_id?

Possible Solution

The token is part of the approval_url, parse the URL and store the token -> payment relationship can solve the problem. But I'm looking for a better solution that doesn't require parsing.

我认为贝宝文档对此并不清楚。但是您可以做一些简单的事情来解决通过返回 url 中的参数传递 de PaymentID 的问题。

像这样： return_url = ' http://www.yourdomain.com/paypal/success/？支付ID=PAY-1234567 '

当 Paypal 重定向到您的站点时，它将返回 paymentID 以及其他参数。

葡萄牙语：

Não acho que isso esteja claro na documentação do Paypal。A solução que eu usei foi simples, eu passo o PaymentID como parâmetro na minha URL de retorno que informo para o Paypal。Assim, quando o Paypal redirecionar para meu site de volta ele matem o parâmetro com o PaymentID que eu tinha passado。

在将用户重定向到 PayPal 批准 url 之前，您必须记住您身边的付款 ID（通常附加在您的用户会话中 - 购物车或订单或作为会话 cookie）。一旦将其与 PayerID 一起重定向回您的返回 URL - 您将需要从您的用户会话中提取 PaymentID 并执行付款。

在第一个 API 请求返回成功响应后，可以使用以下方法在 PHP 中获取 Payment Id：

$payment->getId();

在线代码示例 ( http://paypal.github.io/PayPal-PHP-SDK/sample/doc/payments/CreatePaymentUsingPayPal.html ) 显示了如何发送请求，但是它不包含 getId() 方法。

为了找到这一点，我必须在文件 sample\payments\CreatePayment.php 中查看下载的 SDK 文件，其中包含以下示例代码，显示了此方法的使用：

ResultPrinter::printResult('Create Payment Using Credit Card', 'Payment', $payment->getId(), $request, $payment);

  1. paymentid：

创建付款后，返回json，您可以获得paymentid。像这样：“id”：“PAY-01K00482KX842131HKORKVKY”

  1. payerid：

您可以在用户批准付款后使用 API:GET /v1/payments/payment/{paymentId} 获取付款人 ID，您会在返回的 json 中找到 payerid，如下所示：

{
    "id":"PAY-01K00482KX842131HKORKVKY",
    "create_time":"2014-06-19T09:17:31Z",

                    "payer_id":"H2DKRTTYWW8HS",
