https://ngrok.com
Go through https://ngrok.com/ link to download ngrok and extract that file. Open cmd ( search cmd) Go to directory where ngrok is extracted. Open ngrok from command line ex: c:/ngrok/ngrok.exe [port] or cd c:/ngrok then ngrok 80 ( ngrok [port] ) You will get

Don’t FORGET to make sure your wamp server is open on same port … (how to check -> goto->wampicon->apache->httpd.conf search for port or 80(default) use that for ngrok.exe 80 )
