I wonder if anyone could advise me on how to go about setting up an e-commerce solution that will allow site members to buy credits for music downloads, basically the guy who's site it is wants it all to be done seamlessly on his site without breaking out to a third party supplier?

Is there such an API out there that would allow me to do this?

I will be scripting this in ASP & MS SQL though any advice would be appreciated.

Cheers

Robbie
