通过Paypal的Express Checkout REST API定期付款
我的目标是使用“paypal”作为我们的SaaS的付款方式设置定期6个月和12个月的订阅。我正在使用其余的API，而我无法找到的一件事是如何进行一次性销售并使用PayPal的rest API将代码重新转换为定期付款的工作实现（我读过的是现在可能）。这里是我们在哪里：通过Paypal的Express Checkout REST API定期付款
我有一个工作advanced server integration使用贝宝的Express Checkout REST API进行支付。
我按照上面的链接说明的代码示例创建了一次性销售，以及在paypal中this example中显示的内容。我试图将这两个步骤过程转换为包含账单协议创建和执行调用，但打开用户登录PayPal的光窗口正在停止，出现错误消息“事情似乎没有目前正在工作，请稍后再试“。这里是我的JavaScript代码，它与工作示例几乎完全相同，但具有不同的路线。
paypal.Button.render({
// Set your environment
env: 'sandbox', // sandbox | production
// Wait for the PayPal button to be clicked
payment: function(resolve, reject) {
// Make a call to the merchant server to set up the payment
console.log("button clicked")
return paypal.request.post('/payment/paypal/subscription', {amount: '0.02'})
.then(function(res) {
resolve(res.payToken); #--WHERE I'M GOING WRONG
})
.catch(function(err) { reject(err); });
},
// Wait for the payment to be authorized by the customer
onAuthorize: function(data) {
// Make a call to the merchant server to execute the payment
return paypal.request.post('/payment/paypal/execute', {
data: data,
paymentID: data.paymentID,
payerID: data.payerID
}).then(function (res) {
if (res.state == "active") {
document.querySelector('#paypal-button-container-server').innerText = 'Payment Complete!';
} else {
console.log(res);
alert("Payment could not be approved, please try again.")
}
});
}
}, '#paypal-button-container-server');
我可以告诉我在付款功能上出错了，即resolve(res.payToken)。我不知道我应该传递给这个函数的v1/payments/billing-agreements响应中的哪些数据，但是已经尝试了profile_id和approval_url（实际的href - “href”：“https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=EC-XXXXXXXXXXXXX”）。
我哪里错了？如果这是可能的，我觉得自己是做这项工作的一个工作示例，但是我想知道它是否无法像我这样做（在这种情况下，它可能需要通过Payflow完成？）。
注意：我完全理解计费协议和计费配置文件，而我的问题不在REST API中。除了工作一次性销售实施之外，我可以制作所有必要的结算资料/协议（通过Postman进行验证）。
以下是来自v1/payments/billing-agreements沙箱呼叫的响应，如果有人能指出其中的正确数据段。

的REST API的仍然传回的快速结帐的URL，但为了你需要传回批准URL中找到的令牌checkout.js前端集成使用。您可以解析此URL并获取服务器上的令牌部分，并在调用resolve方法之前将其返回或传递给它。
即
approval_url = {
"href": "https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=EC-XXXXXXXXXXXXX"
}
var token = "EC-XXXXXXXXXXXXX";
resolve(token);
@DNestoff您好，我有同样的问题，你是如何能够解决它 –
@KoredeLawrenceOluwafemi我也想这样做。任何人都知道吗？ – kspearrin
