Python scrip to get public_url from ngrok using API.

First of all what is ngrok? 
ngrok exposes local servers behind NATs and firewalls to the public internet over secure tunnels. This can be used by developers who want to run webhooks with https if you dont have a local ssl certificate. For example telegram, Facebook etc use webhook but they only allow ssl.

The script

after setup the ngrok in the local machine you can run the ngrok command to start the tunnel. in my case i run the ngrok as a service which i have explained in my previous post.

After the service is running you can run the python script or your preferred to fetch the public_url from ngrok which can be use to automate the process. For example Telegram Bot with webhook enable only communicates with https urls so from this method you can get the randomly generated https url to use in such scenarios.

In case if you have a doubt about usage of ngrok and automation please give comment…
