You are free to use each operation (HTTP method) as you wish.

**FastAPI** doesn't enforce any specific meaning.

The information here is presented as a guideline, not a requirement.

For example, when using GraphQL you normally perform all the actions using only `POST` operations.

        // The presence of serialVersionUID is verified at compile time
        // and the exception extends RuntimeException which is Serializable
        assertTrue(exception instanceof java.io.Serializable);

**GraphQL** résout des cas d'utilisation très spécifiques.

Il présente des **avantages** et des **inconvénients** par rapport aux **API web** classiques.

Assurez-vous d'évaluer si les **bénéfices** pour votre cas d'utilisation compensent les **inconvénients**. 🤓
