This component can handle two types of PayPal transaction, Express Checkout and Direct Payment.

Express Checkout

https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/e_howto_api_WPGettingStarted

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 the purchase, call Paypal::doExpressCheckoutPayment() which then completes the payment.

Direct Payment

https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/e_howto_api_WPDirectPayment

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.

Notes

Do not store any credit card data, numbers, dates, CVV numbers etc. in your database, sessions, cookies.

Ensure you understand the legal requirements regarding PCI compliance when handling card data.

Enjoy!
