Hi,
In this blog post, I would like to show how to create a REST API and how to apply MVC1 routing to handle different requests simply from a controller class.
For that, first we will create a handler and controller class for the REST structure. Then we will add an MVC1 controller class and model class to process business logic.
And finally, we will create a service to handle REST requests.
At the end of the post, there are web browser, Postman, and ABAP consuming examples for the same REST API.
To read more about SAP REST, have a look at REST Tutorial .
Let's start.
Create the following structures ;
Now we will create classes.
Call Stack for a call
