# Solicitar token de acesso

Retorne um token de portador OAuth 2.0 para uma conta de serviço da API.

Os tokens são emitidos usando a concessão de credenciais do cliente, que autentica sua conta de serviço em vez de um usuário individual.

## Request a token

> Exchange your Base64-encoded service account credentials for an OAuth2 access token.

```json
{"openapi":"3.1.0","info":{"title":"Authentication","version":"1.0.0"},"tags":[{"name":"Authentication","description":"Tokens are issued using the client credentials grant, which authenticates your service account rather than an individual user.\n\nFor a step-by-step walkthrough, see [Generate a bearer token](generate-a-bearer-token)."}],"servers":[{"url":"https://eseye-idp-{env}.auth.{region}.amazoncognito.com","description":"Eseye identity provider","variables":{"env":{"default":"prod","enum":["qan","stage","prod"],"description":"The environment you are working in."},"region":{"default":"eu-west-1","description":"The AWS region your OAuth service is hosted in, for example `eu-west-1` or `us-east-1`."}}}],"paths":{"/oauth2/token":{"post":{"summary":"Request a token","operationId":"get-token","tags":["Authentication"],"description":"Exchange your Base64-encoded service account credentials for an OAuth2 access token.","requestBody":{"required":true,"content":{"application/x-www-form-urlencoded":{"schema":{"type":"object","required":["grant_type","scope"],"properties":{"grant_type":{"type":"string","description":"The OAuth2 grant type.

```

Retorna um token bearer OAuth 2.0 para uma conta de serviço da API.

POST /oauth2/token
```

### Endpoint

```
https://eseye-idp-prod.auth.<region>.amazoncognito.com/oauth2/token
```

Substitua `<region>` pela região da AWS fornecida pela Eseye.

### Cabeçalhos da solicitação

| Cabeçalho       | Valor                               | Obrigatório |
| --------------- | ----------------------------------- | ----------- |
| `Authorization` | `Basic <credentials>`               | Sim         |
| `Content-Type`  | `application/x-www-form-urlencoded` | Sim         |

`<credentials>` é a forma codificada em Base64 de `<client-id>:<client-secret>`.

### Parâmetros do formulário

| Parâmetro    | Valor                | Obrigatório | Descrição                       |
| ------------ | -------------------- | ----------- | ------------------------------- |

| `scope`      | `api/api`            | Sim         | Solicita acesso à API da Eseye. |

### Exemplo de solicitação

```bash
curl --request POST \
  --url "https://eseye-idp-prod.auth.eu-west-1.amazoncognito.com/oauth2/token" \
  --user "${ESEYE_CLIENT_ID}:${ESEYE_CLIENT_SECRET}" \
  --header "Content-Type: application/x-www-form-urlencoded" \
  --data-urlencode "grant_type=client_credentials" \
  --data-urlencode "scope=api/api"
```

### Resposta com sucesso

Uma solicitação aceita retorna HTTP `200`:

```json
{
  "access_token": "eyJraWQiOiJhYmMxMjMiLCJhbGciOiJSUzI1NiJ9...",
  "token_type": "Bearer",
  "expires_in": 3600
}
```

Reutilize o token até ele expirar; depois solicite outro token.

### Resposta de erro

O endpoint retorna HTTP `400` quando rejeita uma solicitação. Um `invalid_client` erro significa que as credenciais não foram aceitas.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.eseye.com/api-reference/api-reference-pt-br/authentication/request-access-token.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
