MCS: Express API, the new feature added in 16.4.1
When we want to create a new Custom API, we have to define the each of the endpoints and, if we want to consume them from Oracle MAX, we have to define the schemas and then add some mock data. Since version 16.4.1 (v3.0), there is a new feature, Express API, where we can create the resources and the schemas easily and declaratively.
I have to say that we can still create the APIs in the old way. But if we want to use Express API, we just have to select that option when creating an API.
