## Vorteile

Wenn Sie die automatisch generierten Clients verwenden, erhalten Sie **automatische Codevervollständigung** für:

* Methoden.
* Request-Payloads im Body, Query-Parameter, usw.
* Response-Payloads.

Außerdem erhalten Sie für alles **Inline-Fehlerberichte**.

## Benefits { #benefits }

When using the automatically generated clients, you would get **autocompletion** for:

* Methods.
* Request payloads in the body, query parameters, etc.
* Response payloads.

You would also have **inline errors** for everything.

## Beneficios

Cuando usas los clientes generados automáticamente obtendrás **autocompletado** para:

* Métodos.
* Payloads de peticiones en el cuerpo, parámetros de query, etc.
* Payloads de responses.

También tendrás **errores en línea** para todo.
