Rails 的 PayPal 小额支付
我发现与其他服务相比，PayPal 的小额支付系统非常有吸引力。根据 this，他们的小额支付范围从 > 0 美元到
此外，经过仔细审查，我发现 Recurly 和 Chargify 等其他服务对于小额支付模式来说成本过高。如果我错了，请纠正我，因为我一直将手指放在 Recurly 的扳机上，直到我通过更仔细地审查 Amazon FPS 和 Amazon FPS 得到这一启示。 PaPal 小额支付交易费用结构。
鉴于这种新的理解，再次，如果我错了，请纠正我，我正在采取一种方法，我必须采用更类似于 SaaS Kit for Rails 的选项（这似乎并不支持信用卡的 PayPal 交易方法）或某种其他类型的支付机制来处理每月订阅交易。
如果类似的话，有人有适合您情况的解决方案吗？您是否听说过或见过适合此模型并且无需构建交易系统的解决方案？或者我最好硬着头皮将其构建在 PayPal 的基础设施和/或 API 之上？
I've discovered that PayPal has quite an attractive micropayment system in comparison to other services. According to this they have a micropayment range from >$0 to
Further, other services such as Recurly and Chargify, I am discovering upon very close scrutiny, are cost prohibitive for micropayment models. Please do correct me if I'm wrong as I had my finger on the trigger for Recurly until I had this revelation from reviewing more closely the Amazon FPS & PaPal micropayment transaction fee structure.
Given this new understanding, again, please do correct me if I'm wrong, I am taking an approach that I must go with an option more akin to SaaS Kit for Rails (which doesn't seem to support this method of PayPal transactions for credit cards) or some other sort of payment mechanism to handle the monthly subscription transactions.
Does anyone have a solution that works for your situation if similar? Have you heard or seen a solution that fits into this model and takes out having to build the transaction system? Or am I better off biting the bullet and just building it atop PayPal's infrastructure and / or API?

据我所知，您应该可以使用 Active Merchant 来实现此目的。
对于定期付款，此处是一篇博客文章当我最初与活跃商家建立贝宝交易时，我提到了很多。它详细介绍了通过 PayPal 设置定期付款以及使用 PayPal 开发者帐户的过程。
As far as I can tell you should be able to use Active Merchant for this.
For recurring payments, here is a blog post I referred to a ton when I was originally setting up paypal transactions with active merchant. It details the process of setting up recurring payments with paypal and using a paypal developer account.
尝试 Active Merchant，您可以在此处查看它的使用情况以及与 paypal 的实现示例：
