## Le processus normal { #the-normal-process }

Le processus normal (par défaut) est le suivant.

Une application (instance) `FastAPI` a une méthode `.openapi()` censée retourner le schéma OpenAPI.

Lors de la création de l'objet application, un *chemin d'accès* pour `/openapi.json` (ou pour l'URL que vous avez définie dans votre `openapi_url`) est enregistré.
