The Leap Plaza APIs are implemented as vanilla XML over HTTP using GET/POST/PUT/DELETE. Every resource, like Post, Comment, etc. has their own URL and are manipulated in isolation. We have tried to make the API follow the REST principles as much as we can.

For more information on REST, refer to the following:

• http://en.wikipedia.org/wiki/Representational_State_Transfer
• http://www.ibm.com/developerworks/webservices/library/ws-restful/

The following diagram provides a high-level view of the way external systems can interact with Leap Plaza.
