+Rename the `.env.example` file to `.env` and update the `AUTHZEN_PDP_URL` variable. The authorization middleware will send AuthZEN requests to `${AUTHZEN_PDP_URL}/access/v1/evaluation` (for the `1.0-preview` and `1.0-implementers-draft` spec variations), and to a both `${AUTHZEN_PDP_URL}/access/v1/evaluation` and `${AUTHZEN_PDP_URL}/access/v1/evaluations` (for the `1.1-preview` spec variation).
 
 Optionally, set the `AUTHZEN_PDP_API_KEY` variable if your authorizer needs an API key. You should prefix it with `basic` or `Bearer` as appropriate. If set, the authorization middleware will add the `authorization: ${AUTHZEN_PDP_API_KEY}` header to every authorization request.
