我的目标是使用Paypal作为我们SaaS的支付方式，设置每6个月和12个月的循环订阅。我正在使用rest API，但我找不到一个可行的实现方法来将一次性销售转换为使用PayPal的rest API进行循环付款（我已经了解到这是可能的）。目前的情况如下： 我已经通过高级服务器集成成功地使用Paypal的Express Checkout REST API进行付款。我按照上面链接中的代码示例以及Paypal 此示例中的说明创建了一次性销售。我尝试切换两步流程以包括账单协议的创建和执行调用，但打开让用户登录Paypal的轻量级窗口却出现错误消息“当前似乎有些问题，请稍后再试”。以下是我的JavaScript代码，与工作示例几乎完全相同，但具有不同的路由。
我能感觉到我的付款功能出错了，具体表现在代码行
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');
我能感觉到我的付款功能出错了，具体表现在代码行
resolve(res.payToken) 上。我不知道从 v1/payments/billing-agreements 响应中应该传递哪些数据给这个函数，但我已经尝试过 profile_id 和 approval_url（实际的 href - "href": "https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=EC-XXXXXXXXXXXXX").
我做错了什么？如果这是可能的话，我感觉我只需要一个工作示例就能让它正常工作，但我想知道如果我这样做不行 (在这种情况下它可能需要通过 Payflow 来完成?)。
注意: 我完全理解账单协议和计费配置文件，并且我的问题不在于 REST API。除了可行的一次性销售实现之外，我还可以制作所有必要的计费配置文件/协议 (通过 Postman 验证)。
以下是来自v1/payments/billing-agreements 沙盒调用的响应，如果有人能指出其中正确的数据，请告知。{
