I recently presented at Oracle OpenWorld on the subject of REST web services in PeopleSoft.  REST based web services were introduced in PeopleTools 8.52 and I'm hoping this series of blog posts will help newcomers to both Web Services and REST.

What is REST?

REpresentational State Transfer (REST) is a style of doing Web services that is becoming increasingly popular among web developers due to it's simplicity over SOAP and other methods.

REST follows 4 basic principles
1) All content has a unique id by which it is referenced (URI)
2) services are invoked using standard WWW operations of GET, POST, PUT, DELETE
3) all REST services are stateless in that they retrieve a representation (copy) of the content requested
4) REST is synchronous only. Designed for point to point communication

You can invoke a REST web service simply by using it's URI.  For example an example REST web service to GET PeopleSoft operator details might look like this.
