How Paypal Payment Gateway Integration works:

Your website >> Your checkout page >> Paypal.com >> Your payment Success/Cancel page

This is the basic architecture of Paypal payment processing. It's really easy to integrate Paypal as your online payment processor. You need to know database driven dynamic web page scripting using any server side scripting language. Paypal accepts a set of variables to process a payment, and after payment completion, it returns another set of variables (including the existing one) to your website. Now your checkout page should be used to pass those variables to paypal.com. This can be done using an html form. The form should post a set of specific variables to paypal.com. Those variable contains information, like total payable amount, sold item name, item number, paypal email of the payee, payment success page url, payment cancel page url and lot more. Moreover, for good practice, the checkout page should start a session (or set a cookie) which contains a secret string. Finally after the payment, paypal.com returns the visitor to payment cancel page or payment success page, depending on the status of the payment. So, your payment success/cancel page should be dynamic. The payment success page will verify the session (or cookie) created by checkout page and will confirm, if this page is accessed after a successful payment, or directly. Paypal.com has returned a set of variables using post/get method to this success page. So this page will now verify if the payment status is completed and the received amount is same as the charged amount or not. If yes, the success page will alter the database or send some email notification to concerned ids. And finally it'll destroy all the sessions created by checkout page. The cancel page can alter database (like: update orders set status='Due' where orders.order_id #). This page will similarly destroy all the sessions created by checkout page.

Payment gateway integration saves lot of time and effort spent while standing in queues for making payment. An individual can do online payment anytime and from anywhere. The things he need is an internet connection, computer, and the credit card. Another advantage is that automatic tax calculation is done even before making the transaction.
