## Die normale **FastAPI**-Anwendung { #the-normal-fastapi-app }

Sehen wir uns zunächst an, wie die normale API-Anwendung aussehen würde, bevor wir den Callback hinzufügen.

Sie verfügt über eine *Pfadoperation*, die einen `Invoice`-Body empfängt, und einen Query-Parameter `callback_url`, der die URL für den Callback enthält.

Dieser Teil ist ziemlich normal, der größte Teil des Codes ist Ihnen wahrscheinlich bereits bekannt:

Importe `Form` de `fastapi`:

{* ../../docs_src/request_forms/tutorial001_an_py310.py hl[3] *}

## Defina parâmetros de `Form` { #define-form-parameters }

Crie parâmetros de formulário da mesma forma que você faria para `Body` ou `Query`:

{* ../../docs_src/request_forms/tutorial001_an_py310.py hl[9] *}

                }
                return createMockRescorerBuilder();
            }
        };

        // Test normal case
        Map<String, Object> normalParams = new HashMap<>();
        normalParams.put("normal", "value");
        assertNotNull(queryRescorer.evaluate(normalParams));

        // Test exception case
        Map<String, Object> exceptionParams = new HashMap<>();

# GraphQL { #graphql }

As **FastAPI** is based on the **ASGI** standard, it's very easy to integrate any **GraphQL** library also compatible with ASGI.

You can combine normal FastAPI *path operations* with GraphQL on the same application.

/// tip

**GraphQL** solves some very specific use cases.

It has **advantages** and **disadvantages** when compared to common **web APIs**.
