#### Do czego służy OpenAPI

Schemat OpenAPI jest tym, co zasila dwa dołączone interaktywne systemy dokumentacji.

Istnieją dziesiątki alternatyw, wszystkie oparte na OpenAPI. Możesz łatwo dodać dowolną z nich do swojej aplikacji zbudowanej za pomocą **FastAPI**.

Ela inclui uma forma para autenticação usando “third party”/aplicações de terceiros.

Isso é o que todos os sistemas com “Login with Facebook, Google, Twitter, GitHub” usam por baixo.

### OAuth 1

Havia um OAuth 1, que é bem diferente do OAuth2, e mais complexo, isso incluía diretamente as especificações de como criptografar a comunicação.

Não é muito popular ou usado nos dias atuais.

participant execute as Funktion ausgeführt

    rect rgba(0, 255, 0, .1)
        code ->> function: say_hi(name="Camila")
        function ->> execute: führe Code der Funktion aus
        execute ->> code: gib das Resultat zurück
    end

    rect rgba(0, 255, 255, .1)
        code ->> function: say_hi(name="Camila")
        function ->> code: gib das gespeicherte Resultat zurück
    end

Eu estive evitando a criação de um novo _framework_ por vários anos. Primeiro tentei resolver todas as funcionalidades cobertas por **FastAPI** usando muitos _frameworks_, _plug-ins_ e ferramentas diferentes.
