# Autenticações

Um processo de autenticação pode abranger todas as validações realizadas de acordo com a política estabelecida quando o SDK foi inicializado. Essas validações e suas análises podem incluir dados sobre os contextos nos quais o usuário estava situado no momento da solicitação. Em seguida, com base na política definida e nas regras de validação, o status da autenticação é determinado.

{% hint style="warning" %}
Todas as chamadas à API são autenticadas e devem ter o token ao lado do `Bearer` prefixo no `Authorization` cabeçalho da requisição. Chamadas com um token de acesso ausente ou inválido retornarão o código de status **401** ("Não autorizado").
{% endhint %}

O token usado para fazer solicitações à API é o **token de acesso** [gerado de acordo com estas instruções.](/caf-api/caf-api-pt-br/api-smart-auth/authentication.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.caf.io/caf-api/caf-api-pt-br/api-smart-auth/available-resources/authentications.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
