PHP / PayPal / Payment Integration

Hi Chaps,

I’m building a simple on-line clothing shop and I’ve got to the payments bit and need a bit of advice.

I’ve checkedout PayPal IPN and can figure out how it all links together, but I’m wondering if there is something similar that doesn’t redirect to the PayPal site and resides within your domain.

Any guidence would help a lot.

Cheers

Paypal Pro provides a API for making silent payments:
