One of the example views showcases sending requests to a remote server. If you want to use that functionality, you will need to start a local server to echo the response back to the browser.
Since that view uses the [proxy/forward-to](https://docs.commercetools.com/merchant-center-customizations/concepts/integrate-with-your-own-api) MC endpoint and it only allows to forward requests to an external service through HTTPS protocol, we need to start that kind of service locally.
You can use a secure local tunnel to help with this context. For instance, using ngrok.
The local server will listen in port 3003 by default (you can change it with the PLAYGROUND_SERVER_PORT environment variable). You will need to use it when starting the local tunnel.
When using the tunnel, you will need to configure some environment variables with the domain assigned.
Once you get the tunnel domain, head over the .env.local file (in the root directory) and make sure you use it in these variables:
PLAYGROUND_API_AUDIENCE="<tunnel_domain>"
ECHO_SERVER_URL="<tunnel_domain>/api/echo"
Once you did that, you also need to start the local server with this command:
yarn start:server
