Exposing Local Instance
There are situations when you would like to expose your local environment to external clients, for example:
- Show your project to the manager.
 - Integrate with the new payment gateway, which requires a return URL.
 - Test the app deployed in the cloud.
 
To achieve that, you need a service for redirecting the traffic. Such service is delivered by ngrok and localtunnel. Both are great for our use case, and you can choose any of those services.
Using ngrok
- Append ngrok URL to 
ALLOWED_CLIENT_HOSTSenvironment variable. - Start Saleor on your machine.
 - Follow ngrok installation guide.
 - Start a tunnel in your command line 
ngrok http 8000. - Your server is now exposed under ngrok domain (for example: http://92832de0.ngrok.io). Copy that address.
 - Enter ngrok URL at Site Settings configuration.
