Pro PayPal E-Commerce (Expert's Voice)

All of the information that this book covers is available directly from PayPal at no charge, but then rendering it useful would be a major task indeed. Mr Williams has done that major task, and more, and made it accessible and useable by those who want to integrate PayPal's capabilities into their own eCommerce offerings, without having to build, support and (no small feat) pay for the development of the required infrastructure. PayPal may well be the National Cash Register for the 21st century, and while this book lacks the dazzle of a John Patterson, its relatively prosaic ways cover what has to be covered in detail and with commendable clarity. The first of the nine chapters is certainly required reading, but the remaining chapters can be studied on their own, allowing a software developer to focus on the implementation that immediately meets that business' specific requirements. This is a reference book for anyone who wants to use PayPal programmatically, with well presented and documented examples and descriptions, written for software developers by a software developer.I also recommend Professional Web APIs with PHP: eBay, Google, Paypal, Amazon, FedEx plus Web Feeds as a companion reference book, with an excellent and very readable overview of the PayPal system.

The book did a good job of covering everything EXCEPT the Paypal API. It had a smattering of samples in PHP, Java, C#, VB, and Perl up until that point.Once the PayPal API is discussed, there are only a couple of samples and everything in Java despite the growing (and perhaps exceeding) popularity of PHP for website development. While not entirely the author's fault given the poor shape of PayPal PHP SDK, it was disappointing that so little time and explaination was given on how to use Paypal's API. If you're looking for help integrating PHP with the Paypal API for Website Payments Pro or Express Payment, you're out of luck. This book won't help.This is unfortunate since the Paypal API is the most complex part of integration and perhaps the reason you would buy a book like this since many of the other integrations such as IPN are fairly easy by comparison.The book does do a good job of working you through IPN integration, so if that's what you need, then this book will help.Having had to now try and learn the PayPal API on my own, it does seem like it's fundamentally 'over-complex' and Paypals SDKs do little to hide the complexity. Perhaps the Java SDK is in better shape, but the PHP one is a bear to get configured and working correctly

this is a book for people that work with pc systems, not intended merely for user of paypal.i m a user and do not have he system knowledge, but found the book helpful and ilustrative.Roberto Anez Nava
