I made a site and I need to integrate PayPal's MassPay API. I'm a coder but I never done this before so I need some help.
What I want to do is to users pay $5 before downloading a file from the site, after successful payment they can download it. After the $5 is payed I want to send $4 to uploader of file. I think this is made with the Mass Pay API.
I need a really experienced programmer who has worked with paypal before.
