Introduction - If you have any usage issues, please Google them yourself
This book is primarily for software developers. I assume you have a basic understanding
of Internet technologies and programming techniques. Code samples are scattered
throughout the text and are provided in numerous languages, so fluency in languages
such as Java and PHP will help you get the most value from the book. All the code samples
in this book, as well as additional code that isn’t included in the text, are provided
in the Source Code/Download section of the Apress website at www.apress.com.
If you are a business owner or entrepreneur with little to no programming experience,
however, there is still a significant amount of information you can glean from these
pages. While a good portion may be too technical for your interest, this book provides
details on almost all PayPal technologies, and as such can give you a better sense of the
type of work that would need to be done in order to integrate PayPal into your grand
schemes, even if you ultimately won’t be the one hacking out the code.
