ORDS REST Modules with PL/SQL

Here is one of the best references I’ve found for creating ORDS REST services with PL/SQL.

There are examples of the various methods (GET, POST, PUT, DELETE), as well as examples for authentication.

One thing to note is that REST modules created with PL/SQL are separate from those created in APEX. Therefore, modules created in APEX cannot be edited with PLSQL.

Creating REST modules in PL/SQL is the more robust method, as it allows you to customize it better. Also, having any sort of logic inside stored procedures and database objects is always a good idea.
