### Same Schema for Input and Output Models in Docs { #same-schema-for-input-and-output-models-in-docs }

And now there will be one single schema for input and output for the model, only `Item`, and it will have `description` as **not required**:

Definisi skema ini termasuk jalur API anda, parameter yang bisa diterima, dll.

#### "schema" Data

Istilah "schema" bisa juga merujuk ke struktur data, seperti konten JSON.

Dalam kondisi ini, ini berarti attribut JSON dan tipe data yang dimiliki, dll.
