# Make an authenticated request

To make an authenticated request, fill the header `Authorization` with this data (don't forget to add "Token " before your key) :

```
Token YOUR_API_KEY
```

In oder to test authentication on Sandbox environment, you can try the following request, that returns all transports from your company account:

```
GET https://sandbox.dashdoc.eu/api/v3/transports/
```

You can request your Dashdoc project manager to have your sandbox account created.

The result should be something like this :

* response status : 200 OK
* response body:

```
{
    "count": 4,
    "next": null,
    "previous": null,
    "results": [...]
}
```
