Overview
The PaymentKeys Application Framework takes advantage of several recent advancements in web service standards and technologies that are gaining wide-spread adoption because they result in web API's that are easier for programmers to implement and debug, provide better security, and result in lower message overhead and faster data communications on high-volume transaction systems. Traditional standards in web service technologies are also supported and utilized where they make sense to improve the overall easy-of-use and funcationality of the API.
These technologies include:
- REST - A simpler, lighter approach to making API requests via HTTP
- JSON - A light-weight data-interchange format
- HMACSHA1 - A cryptographic hash technology that provides both sender and message authentication
- XML - An established data-interchange protocol
- WSDL - An established web services tool utilized in this API for stubbing client object (class) structures.
Although this list of acronyms and the associated linked documents may look daunting, these technologies are actually very simple to understand and implement. The rest of this wiki will give clear guidance for the template, structure and methods of making an API call to the PaymentKeys Application Framework servers utilizing these technologies.
Sample code is provided within the specific documentation for every API command to simplify the adoption of the PaymentKeys Application Framework into your software application.
