     Alternatively, if your reverse proxy prevents you from accepting `POST` requests, you can configure Mintlify to send requests directly to your backend with the `api.playground.proxy` setting in the `docs.json`, as described in the [settings documentation](/settings#param-proxy). When using this configuration, you will need to configure CORS on your server since requests will come directly from users' browsers rather than through your proxy.
