Express Checkout
First, set some basic information about the transaction you want to perform, amount, currency etc. and call Paypal::expressCheckout().
The user is redirected to PayPal where they log in, they are then redirected back to your site (to the return URL).
You can then use Paypal::getExpressCheckoutDetails() to fetch basic customer information, their billing address etc.
If they are happy and want to proceed with purchase, call Paypal::doExpressCheckoutPayment() which then completes the payment.
Direct Payment
The customer enters their billing information on your website (SSL required) and you use this to call Paypal::doDirectPayment() which will attempt to bill their card.
