paypal - Is there a way to create postpaid subscription with paypal?

Question

Is there a way to create postpaid subscription with paypal ? Basically what I want is to charge some amount at the end of the month from user paypal account.

That amount of money depends on how much minutes he spend on our service during that month...

Answer 1

使用 Payments 标准订阅，您无法更改计费金额。通过 Express Checkout 使用定期付款，您可以更改金额，但只能更改 20%。

如果您通过 Express Checkout 设置计费协议，则可以使用 Reference Transaction API 调用向客户收取您需要的任何金额。需要在帐户上启用其他功能才能使用参考交易。

在 SetExpressCheckout 调用中，您定义计费协议条款，当您提交 DoExpressCheckoutPayment API 调用时，您定义的计费条款与您在第一个 API 调用中包含的完全相同。
