access api appear band buttons cart customize experience features inside restyle seamless service services site user website

I'm wondering if we can include your service in our band's site, access your services features via some API, and restyle the UI so the user experience is seamless to the user?

You don't need an API for that. The "E-junkie Cart Buttons" that we provide make the cart appear "inside" your website. Please see http://www.e-junkie.com/ej/demo.php.

You can also customize the cart (please see http://www.e-junkie.com/ej/help.custom-cart.php)
