This worked example will show you how you can use a REST service test tool, like Postman, to execute REST services on Oracle EBS 12.2. It will guide the end user to locate and use seeded authentication and authorization services, and show an example of how to enable a service (e.g. get a list of available payslips) and to test the execution of these in Postman. There is an optional section to try, or at least read through, to give you an insight into to just some of the seeded services you can expose on the Integrated SOA Gateway on an eBusiness Suite 12.2 instance.
