### Obtaining a token

To obtain a token you should POST to `http://localhost:3000/oauth/token`.

#### With *password* grant

You need to include the client credentials in request headers and the user credentials and grant type in request body:

* **Headers**
    * **Authorization**: `"Basic " + clientId:secret base64'd`
        * (for example, to use `application:secret`, you should send `Basic YXBwbGljYXRpb246c2VjcmV0`)

    * **Content-Type**: `application/x-www-form-urlencoded`
* **Body**
    * `grant_type=password&username=pedroetb&password=password`
        * (contains 3 parameters: `grant_type`, `username` and `password`)
