In my app, every month I have to send money to the people who sell products through my app. I use active merchant to receive money. Can I use it to send money automatically using PayPal? How? If can't, what are the alternatives?
I would look at something like Stripe but if you are married to PayPal, this seems to have a pretty clear explaination: http://dimaspriyanto.com/2010/05/01/simple-paypal-transfer-using-active-merchant/
