UKOUG APEX SIG 10th presentation by Colin Archer This demonstration will give an overview of how to create RESTful web services using the ORDS PL/SQL API package, how to protect them using OAuth2.0, and how to use them within an APEX application. In the first part of the demonstration, I will walk you through the steps involved in creating and testing some simple ‘GET’ and ‘POST’ method web services. I will then demonstrate how to protect the web services using roles and privileges, and how grant access using OAuth2.0 and client credentials. In the second part of the demonstration, I will show you how to use the web services inside an APEX application, including the use of client credentials to access ones that have been protected with OAuth2.0
