Processing payments over the Web is not a trivial task. There are many issues to consider, including security, reliability, and availability. PayPal is one of the leading providers of e-commerce services. It is a public company, the services are available in many countries, and it offers great security and reliability. Plus, the service is free (PayPal charges a fee per transaction, like credit card companies).
ComponentOne PayPal eCommerce for ASP.NET controls work by trapping click events, building a custom URL string with information about your business and the item being purchased, and redirecting the browser to the PayPal site, where the transaction is processed.
This design shields you and your site from the complexities of designing and maintaining the e-commerce infrastructure, while at the same time giving you total control over the Web store itself.
The PayPal pages where your customers make the payments are not on your site, but they can be customized with your logo, so your brand is always visible and the user experience is smooth and comfortable.
The PayPal Web site (www.paypal.com) provides a wealth of information on the services provided by PayPal. There is also a section devoted to developers, PayPal Developer Central (http://www.paypal.com/developer) that you should definitely visit. Because the PayPal eCommerce for ASP.NET controls use the standard PayPal protocols, all the information on the PayPal site is relevant to PayPal eCommerce for ASP.NET users.
