# Authentication

{% hint style="success" %}
To access the Dashdoc API, you must authenticate each request using an API token. This token should be included in the HTTP header of your requests.
{% endhint %}

### How to Include the API Token

For all API requests, the API token must be provided in the `Authorization` header. The format for the header is as follows:

```http
Authorization: Token YOUR_API_TOKEN
```

### Example Using cURL

{% code title="Example of curl authenticated request :" %}

```bash
curl -X GET -H "Authorization: Token 5a4d02fad3975c169e9f538d8e733ead4069703x" "https://www.dashdoc.eu/api/v4/transports/"
```

{% endcode %}

### Example Using Postman

### How to generate an API token ?

You can obtain the API token from the Dashdoc web app:

{% content-ref url="/pages/Nr1pz0NrQtuhEBO7vEAb" %}
[Get the API token](/docs/integrate-your-software/setup/get-the-api-token.md)
{% endcontent-ref %}

{% hint style="warning" %}
Keep in mind that an API token is **tied to a specific company**, giving access to all company's data. You can only have one active API token at any time.
