PayPal Micropayments for Rails

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 revel开发者_运维百科ation 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?

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.
