"fqdn": "_acme-challenge.domain.",
"value": "LHDhK3oGRvkiefQnx7OOczTY5Tic_xZ6HcMOc_gmtoM"
}
```

```json
{
"domain": "domain",
"token": "token",
"keyAuth": "key"
}
```

Basic authentication (optional) can be set with some environment variables:
- `HTTPREQ_USERNAME` and `HTTPREQ_PASSWORD`
- both values must be set, otherwise basic authentication is not defined.
