PayPal setup with multiple receivers

Question

I'm trying to make paypal payments available on my site where different people can sell their stuff. I know a lot of websites let you specify what your paypal address is and you get paid. I have paypal pro set up, but the receiver info in paypal payments pro is API username, API password and API signature. How can I change this to just use an email address for the receiver so I don't have to ask for all users' API info?

Thanks

Answer 1

This won't work with Website Payments Pro. You'll need PayPal Express Checkout or PayPal Adaptive Payments which allows for split or split & chained payments, respectively.

Answer 2

There is no way of direct sending the money from A to B on your site without having a signature of B and without any kind of interaction with B. And there are business reasons for why it is impossible.

If asking the receivers signature is not an option to you, you can transfer the money as A->C->B, where C is your account (that is, making users to send money to you, and then sending the received money to the needed receivers).
