## Return the token { #return-the-token }

The response of the `token` endpoint must be a JSON object.

It should have a `token_type`. In our case, as we are using "Bearer" tokens, the token type should be "`bearer`".

And it should have an `access_token`, with a string containing our access token.

## Devolver el token

El response del endpoint `token` debe ser un objeto JSON.

Debe tener un `token_type`. En nuestro caso, como estamos usando tokens "Bearer", el tipo de token debe ser "`bearer`".

Y debe tener un `access_token`, con un string que contenga nuestro token de acceso.
